Corroseal-82320 Water-Based Rust Converter Metal Primer, Rust Converter - 1 Qt

My surround porch roof is supported by steel posts. After 20 years, they had rusted some. I used some debriding but most of the rust was very. Superficial. Put this on. Waited for it to dry. Had to put a. Second coat on some spots. Now a year later after painting over it no problems. I have also used ot on rusty gates, etc. It seems to really work well.

Work really well to seal off rusted area

I’ve used this stuff for years and for treating metal it’s the best. Absolutely imperative you read the instructions

I applied this to my vehicle on a cold evening, around 40 degrees F and once it dried there were white chalky patches of the paint. I reached out the manufacture and they said thye believe it is because it was applied below 50, but it does no say anywhere on the bottle or in their online instruction that the product has this limitation! areas that I applied when it was warmer came out great, so I am giving 4 stars, but a bit of a frustrating experience.

I really liked this. The color changed worked great and seems to have stopped the rust

This stuff is awesome! I got it to restore a truck frame but have used on countless other things. Seals and becomes rock hard and then just paint over. Make sure you follow directions though! If it is still purple then it didn't work and you need to apply more! As with anything like this, prep is key!

I have used another product for a number of years dealing with rust as it occurs on a Freighliner chassis and tow gear and things. I've been surprised at how well it has worked. This product claims to convert rust in the same way but is water based instead of oil based. was a little skeptical about this being a water based product but read some reviews by professional restoration types on other websites that sounded excellent so gave it a try. First, water cleanup is definitely a welcome change. As to the product, the reviews of its long term effectiveness were good. I have no reason to doubt them but haven't used it long enough to confirm them, I have used it in a number of places over the past couple of months and been pleased with the result whether significant preparation was needed on heavy rust or just normal maintenance on light rust as it begins to occur. Follow the directions, including the additional coats indicated by the colors it presents as it dries and I think you will like the results. It will dry to a durable deep black finish somewhere between gloss and semi-gloss. It serves as a primer for paint at that point although the finish looks nice enough, even when applied with a brush ,that the only reason I think I'll paint is to make the adjacent surfaces look as nice as this turns out. I'm even considering just using this although it would make for an expensive paint where rust treatment isn't required. I did some black enameled panels where there was rust I brushed out in a few place and no rust in other places. I coated the whole panel and it looks nice and uniform in the previously rusted areas as well as the rest of the panel. I will definitely be purchasing more of this.

I have Rust issues after only a few weeks even though it was Sand Blasting.
