Rated 5 out of 5 by from Easy To Apply - Sands Easily - Time Will Tell This product is easy to work with as long as you take your time and don't make a mess. I am refinishing the steel chassis on a small British sports car so there are a lot of tubes in a small space. I gave everything a good wipe with Eastwood PRE Painting Prep. Then the Encapsulator brushes on easy and covers well. I let the first coat dry for a few days and then I went back to hit the spots I missed and give everything a second coat. I was very happy to see how easy the sanding was. I used 400 grit on a soft backing pad and it cleaned-up and scuffed very nice. I just got done with the second coat and I'm very pleased with the results, especially knowing I can sand it nice and flat before I apply the Eastwood's Chassis Black Satin. Hopefully this product will do its job and preserve my little car for many years into the future. I'll give it five stars based on my trust in Eastwood's quality and promise of a rust-free future.

Rated 5 out of 5 by from Excellent product!!!! This rust encapsulator is great!! I spent a long time searching for the best product to get to prevent rust on the underside of my Runner all the ones I found with water-based and in my mind water-based would not work well for rust I ended up finding this after some searching and this stuff is absolutely outstanding!! I just grinded rust off with a wire wheel and painted over it with the rust encapsulator one coat goes on heavy it's much thinner than I was expecting it to be so I made a pretty bad mess all over but this stuff is awesome I can't say that enough! It's been on there only a week and to tell that it's as great as I think it is we have to test the longevity of the product but initially I couldn't have made a better choice.... make sure when you do this job to have a Tyvek suit or something on I got a bunch of it on my arms and for the life of me I cannot get it off I tried bar soap and dish soap right away didn't work then I tried nail polish remover didn't work then I tried a chemical they have at work for removing dies and paint and then I tried goop orange cleaner none of that work eventually I just peeled most of it off after it dried I still have some even now and it's been a week.... but in my mind that says if there's not any chance of me even scrubbing it off my arms it will never come off my Runner frame. All of the photos are a single coat before and afters.... THIS IS A VERY RECOMMENDED PURCHASE!! I WILL MOST DEFINITELY BE BUYING THIS AGAIN!!

Rated 1 out of 5 by from Didn't make it a year Used this less than a year ago. About the ONLY thing this encapsulates is your cash. I live in MN where rust runs rampant. Followed directions to no avail. If I could get my cash back I would.

I'm using encapsulator on the inside of jeep tj floor. I want to spray quartz bed liner over it. what is the best method to make sure the bed liner sticks good.

Asked by: sniper_clown
Technically we can not guarantee compatibility with brands we do not sell. Best bond would be to generate a chemical bond. Technically this version of the Encapsulator can be top coated as soon as 4 hours after applying it. It would be highly recommended to test a scrap piece of metal or small section first.

Can I use this on painted trunk areas ?

Asked by: Sueme
Yes, you should be fine with most applications. Just be sure to sand first with 320/400 grit paper and clean and degrease. We have to recommend testing a small area first to ensure a reaction would not occur.

I have some badly rusted rocker panels. I'd like to clean them up and apply this product to stop the rust. Later I'll cut out the worst parts and weld in a replacement rocker panel. Is it safe to weld through?

Asked by: bdbaddog
This is not intended to be welded through. It should be welded first or removed from these areas and some of the surrounding surface where the metal will be heated.
