*Update* It works better if you apply coats until you don't see any more rust after curing. This may take several coats beyond the instructions. Then paint with oil based rust inhibiting enamel. That should do the trick.

Straight no-nonsense video. Thanks for uploading - useful.

Nice video, man! Seems like it's very similar to Rust-Oleum rustwandler, which has been working great for me in Denmark, Scandinavia, where it's VERY humid and the roads are salted every winter. But as you mention in your update, I too found out, that it's imperative to let the stuff cure at least overnight, before you apply more coats of it or paint. Thanks for taking the time to make this video. :)

Thank you for taking the time to do this review. Certainly saved me a lot of time.

awesome topic!

Can this be used on high temperatures like the exhaust pipe under the car??

I have used Corroseal for so many projects... everything from rusty door hinges, wheelbarrows, outdoor furniture, fencing, and of course automotive applications. It is the MOST AMAZING PRODUCT I have ever used. I spent $16 on a 32oz bottle about 10 years ago & I still have about 12oz left!!!! IMPORTANT TIP: DO NOT STORE anywhere that will get HOT, like a GARAGE or SHED. The material at the bottom of the bottle will rubberize & you will lose product.

Does it actually remove the rust or just colored it and cover it?

The area that has some discolor is the area he technically never applied a 2nd coat.... The 1st coat never got to dry then he just spread oxidizing rust mixer around and never used more than 1 brush worth on the 2nd coat when he used 5 on the 1st.....

Good video. Thanks for the info.

Darn great video.. DARN Great video!!

You should go back and treat the rusty side with Ospho. A rust inhibitor, then paint.

Rust never sleeps…

Vht rust converter. Only way to go. Then paint. Then cosmoline. Shuts it down completely and for good.

Needs to be alot thicker and cure alot longer ,I coating my whole truck frame with it and it worked great and has lasted 2 years

Looks like rayhog water based paint ?

I am seeing something that looks exactly like this called "FractionK" and I came on here to find a review for it. (it seems to go on white-ish then turns black, just like corroseal.

Who sells it

The right way to apply this product is to place it in the hopper and grab your sand blaster

Also the half with corroseal had the most rust so just the painted spot looking better wasn't as rusty.

If you look at the video of the before, you will see that the half that rushed through the paint was much rustier than the other side. Not really a fair comparison test. Should have turned the wheel 90 degrees and split the rust instead of leaving the right that was worse and coating it only.

POR-15

doesnt look like you applied seal rust convertercause the part to turn brown to black and i see bronwn.

Rust never sleep

Why roku remote control there? Lol

That wheel was barely rusted. You could have removed that with a wire brush easily. You need to show it on really rusty metal.

What i've learned after countless videos, opinions & "experts" is: rust is like taxes & death- sooner or later, it's going to get you. 🥺

I think your experiment is not a good example you did not have enough rust on there to be converted so when it got exposed to the element the parts that was unrusted and untreated I should say unconverted was exposed that's what you have you didn't you hit not enough rust to be converted that's why I failed

I haven’t been impressed with Corroseal either. Try this same test with Rustoleum rusty metal primer.

Coroseal has done a great job for years on my projects...Wire wheel the LOOSE stuff. That is why this video did NOT show accurate results

I think this test means nothing. Before applying rust converter you should have cleaned the loose rust with a wire wheel. Make all as clean as much with it, degrease it and then apply rust converter. I will bet this time it will prevent rust much better

I think you have to remove the rust first with steel brush then apply the rust converter...
