Expensive product quickly turns to lump of [cr] rubbish – Product worked at about 3 out of 10 . Tried to use 3 months later , My $60 bottle had turned to a solid lump of useless crap. Dont waste your money , There are better products around. Maybe the stuff i have in my cupboard that ive had for years that is green , and was a fraction of the price.!This is the 2nd bottle to do this. Back to the drawing board White Knight. Show details

Difficult product to use – Product had separated. I returned it to another store and it was replaced but second container also had separated. Directions for use state to stir for 5 minutes but 500ml product comes in a plastic container with a small screw top lid. Could not pour product out or stir in container. Once rust converter emptied into a different container and… Read more

stirred thoroughly, consistency similar to a chunky pancake mix and difficult to apply with a brush (as directed). Application not smooth enough for primer/topcoats. Seemed to convert rust once applied. Unsure whether this a product fault or just been on the shelf but had the same problem with products from 2 stores. A product that requires stirring should at least be in a container which allows this.

So easy and fantastic result!! – Got gutters cleaned. Bad news - all gutters rusted and need replacing, on a big house. Fascia ok but needs to be derusted and painted. Couldn’t get a professional to do the job. Now totally understand why. A massive fiddly job using a good quality paintbrush over a few days. Gutter guy removed the gutters and also did the sanding back of the… Read more ·  2

fascia. Over to us before he returns to install new gutters and down pipes ! Degreased and cleaned the whole fascia with meths. Made very very sure to get the rust converter properly ready. (1) Checked it was still liquid and that it hadn’t expired and become hard crystals. (2) Poured it into a big jar and made sure to stir well with an uplifting motion for the whole 5 minutes with a wooden spoon. Extremely easy to apply, went on easily. Very quickly the rusted areas turned black. Photos are before applying primer. Just a small example of a lot of black!! Left to cure for 24 hours and then masked to protect the cream ceiling boards. Have now applied the 1st coat of metal primer in medium grey after stirring that properly too. The fascia looks fantastic. Will do a second primer coat after 16 hours of drying properly - may not need it it but want to make sure it’s great and the paint job lasts for a long time. Will possibly only apply one top coat in our chosen grey after another 16 hours.

Works well if only – My second 500ml bottle has become a solid lump of goo. Brand new from the shop. Day temps are 12-26deg so not frozen. Tried adding water (clean up) to thin the product but no good. Still a slippery solid mass of goo? Like a tub of soft butter. Cost over $50 - wasted. Show details

Unusable White Knight Rust Guard Rust Converter – I bought a new 500ml container of White Knight Rust Guard Rust Converter, but when I came to use it I found it had all but gone solid and was unusable. I threw it away as I did not keep the receipt. I later bought a replacement identical product but did not use it immediately (actual period unknown). When I opened that bottle today I found the… Read more

same issue ie product was almost solid and was unusable. Again, I doubt I will find the receipt and will have to throw that away also. Not happy and DO NOT RECOMMEND THIS PRODUCT!!! Having read other similar reviews, I will never buy White Knight products again.

Not happy with this changed product – The product has changed. I've used the old one for 20+ years. I was not notified about the change except for the label it does not work a swell and it now sticks and look like semi translucent, white cream on paint when dry, did not do this before. very upset about wasting my petrol and time going back and forth to Bunnings for a refund, when I should not have to do, if the product was clearly marked "New Formula"

Beginning of the end for White Night – Absolutely disgusting for a company to change a Formula "at will" and not making it Clear on the New label. After I paid $54 (about $10 more than last time) and the cost of driving 15klms to get it (petrol is not free or cheap) I read the label and you now need to mix if for 5 minutes. WTH? and its now gone to a White pigment color, not Clear.. I… Read more

cannot treat painted or clean up the rust on chrome wheel rims anymore, without being extra careful Not to get it on the black rubber tire because this new formula will not easy come off black rubber, when its dry. HOW CAN ANYONE TRUST A NEW RUST CONVERTER FORMULA, It takes years of use and trial time to see if it actually works. It has taken me 20 years with the Old Rust Guard, now you want me to start again, you got to be joking.

Works well for me – Mixed reviews on here. It works just fine for me on farm equipment, slashers, Tractors. We live close to the coast so salt drift has always been a problem causing rust over the years. Weird that some people find it bad and others good ? Show details ·  1

Directions on product disagree with website – I wish I had looked at reviews before using this product. I stripped and cup-brushed/flap-disc'd a steel project and applied rust guard as per directions on the bottle. After a few days I applied primer and left a day to dry. I noticed bits of primer had a raised look to them even though it was applied to a flat surface initially. I used a scraper… Read more

blade to check the raised parts of primer to discover the primer hadn't stuck to the rust guard. I then checked the white knight website to see if there was any additional information available to explain the issue. I found the directions on the website were different to the directions on the product. I then had no option but to remove all coatings back to bare metal. I then found what a mess rust guard makes if remove with brush or disc at high revs on grinder. My bad experience suggests using a variable speed drill at lower speed with cup brush attachment to minimise the black dust which gets into absolutely everything. Even better, don't waste your time using this product in the first place. If you do then only apply to visible rust and if the rust guard is not a dark black colour then sand it until it is before apllying primer. The directions for this product will land you in a world of hurt and double the time on your project. My next project is going straight to the powder coaters!

I had no problems and very satisfied – I actually got to this site today because I was trying to find out if I can use it on two timber flyscreen doors. I was surprised to see the negative comments. I used it on galvanised steel posts supporting a pergola I had no problems whatsoever. I used cheap paint brushes and threw them away, cheaper than using fancy thinners. I live in the… Read more

outback, generally hot and dry. I had no problems with drying but I did coats on successive days. About a year ago, so perhaps the formula has been changed recently.

Review for White Knight Rust Guard Primer in grey – I went to Bunnings to get some killrust primer and paint for my new welding cart I made from steel. Bunnings said that they don't carry killrust anymore so I bought White Knight Rust Guard Primer and some White Knight squirts top coat. The rust guard goes on thinly and I needed two coats of primer as it just didn't cover in one coat. That wasted… Read more

time. Three days later and the primer is soft so I can't paint it yet. I'm going to get some turps and wipe it off. I have thrown the expensive can of Rust Guard in the bin and will be going back to my old favourite - killrust.

Rust guard, not easy to use but does what it says – I have used this product for many years on my custom bikes and cars. Not easy to use, prep is everything and it takes a week to go hard after topcoat, but when set it is bulletproof. I painted a set of Harley fork lowers with the etch primer and then gloss black, they look great 7 years on. Also painted chrome after sanding and etch, looks great and very hard to chip. Today painted a bike frame, expecting it to be excellent as it looks when wet. Show details

White Knight Spray paint - Poor quality control followed by rotten customer service – Disappointed as this product which was expensive and not at all discounted when I purchased. Got up at 5am to use this product as still to minimise wastage had old packaged product first which Went on fine but new packaged tin had issues when i started spraying as was missing a crucial part to the spray nozzle! This mean’t i had spatters of… Read more

paint going everywhere and after heaps of wasted time and energy to find out it was a quality control fault with the tin as red directional part was missing from spray cap!! I wrote to the manufacturer who are quite lousy as now want me to be further inconvenienced by their poor quality control Issue by having to return to the place of purchase which is a long way from where i live - with the faulty tin and provide proof of purchase just to get a refund of the item! Surely they should offer to send me a replacement tin and sincere apology for inconvenience and wasting my time - this tactic by big greedy companies when clearly at fault needs to be at their expense and not mine! Beware Of purchasing this brand as this is their new packaging product i had problems with so more failty ones are sitting on bunnings shelves awaiting suckers like me!

Doesn't Do What it Says it Will Do – Used this as per directions on my cast iron birdbath thinking there was something in its name. I used a wire brush then metal primer as directed then followed with two coats of this enamel. The birdbath rusted. Show details

Crappiest Paint On The Market – This paint is crap!!! Do not use it. It wrecked 2 of my $200 dollar paint guns. You cant thin it cause it eats the thinners up and it clogs the gun and the gun just sprays air. By brush the coverage is poor and will not surfice your needs. I ended up using Watyl kill rust and that stuff paints and thins like a dream. If you buy this rust guard just throw your money away now.

Rust Guard range – White Knight 'Rust Guard', refers to a range of products which offer different functions. It is principally designed for use on ferrous metals such as iron and steel. The essential process of treating lightly rusted metal involves using three products, Rust Converter, Metal Primer and Topcoat. Follow all instructions at each step if you choose to… Read more

use all three (eg. sand / scrape to remove loose rust and old paint first and lightly sand between coats of primer and topcoat). I found drying time varied depending on atmospheric conditions, the best being low humidity and above 15C, mostly it was touch dry within 30 mins but leave for a few hours to harden off. Topcoat comes in a few different colours both in tin and spray and is compatible with Colourbond colours. Yes, it may be time consuming but produced an acceptable finish. Plan ahead and tackle small sections if repainting a trailer for instance. The spray Topcoat is handy for tricky areas.

Better of the available options – I am not a 'professional'.. i have however restored several vehicles over the years and believe this to be the better of the available options on the australian market. Rust converter is not a miracle worker, it is however a useful tool to get rid of light surface rust before paining. I would suggest you follow the instructions of any product carefully. Quite powerful concentrate Sticky afterwards

ineffective – I used this product on the many surfaces without success. Steel posts, trailer, custom orb roofing, even inside tables. All have started to rust in 8 months. As a professional have used the correct procedures. Left for the correct time before priming . Was used under both acrylic and oil based paints. I have always had a top regard for their… Read more

products as I think they make good paints. Maybe an off batch definitely did not work this time or maybe as good as they say

The review is for the rust converter and not the product in the picture for the solvent. Richard
