Blaster Surface Shield Complete Corrosion Protection for Long Lasting Automotive Rust Inhibiting Undercoating Applications, 12 oz Aerosol Can, Pack of 6 Spray Cans

I like this under coating very well, it's good quality and works great, I spray the frame and everything else every two years, I see no rust and this is a really good price, the seller got it to me on time no problems at all yes I would recommend the seller and the product

This stuff is fantastic. protects for years ,stays soft and doesn't wash off. also doesn't smell bad. May be the best rustproof on the market!

I use this on lathe chucks and the ways of my metal working machines. They are stored in a shop that is not heated or cooled unless I'm actually working there. That means parts that aren't--and can't be--protected by paint are very prone to corrosion due to condensation.This stuff works great to prevent rust! After cleaning-up the machine after working, I spray the ways, chuck, and other bare metal surfaces with Blaster Surface Shield. It hangs on very well, and does an excellent job of protecting against rust. It's a little pricey, but it has completely stopped the rust I was occasionally finding after wiping down my machines with way oil or motor oil.

I read and watched a dozen reviews before I bought it and I was not disappointed. I WOULD recommend this for a DIY undercoating.Pros- easy to use, not expensive, works itself into the crevices, stays put, easily washes off of the drivewayCons- gets a little messy (wear gloves), nozzle clogs (blow out w/ air), hard to spray into box frame

Good stuff it goes on and stays on. I coated the under side of my new Toyota Tacoma and it took less than 2 cans. It goes on and does not trip down in your face it sticks really good. The smell does not bother me at all.

I saw a ton of reviews saying this stuff was great and competitive if not better than similar products.I picked up a case and it's pretty much unusable. Shaking the cans when it is 70-75F out and they refuse to spray. I have to heat a pot of boiling hot water and toss them in that. And even then I have to have 3 cans heating at a time because after their temp drops a bit they stop spraying and I have to swap to the next can with decent pressure.Then once the cans feel to be about half empty they are no longer usable. No matter how much you shake them or how much heat you put into them. At least not heating with water, I'm not putting a torch to these to try and use them.Save your money, pick up one of the competitors.

I'll update my review after a year or two if it holds up well underneath my truck. I assumed most people didn't have any issues with the cans and just those that did left reviews about it. I also had problems with them.Here's what I did to get around it. One can oozed half the product out around the nozzle when trying to spray. I pulled the nozzle off and part of it was broken where it goes down into the can. No big deal, just pull one off a different can and good to go. All of them had issues clogging up throughout. Usually it would be fixed by simply pulling the nozzle off and putting it back on. If that didn't work I pulled the nozzle back off and used an air hose to spray into both ends of it and that worked.I didn't have any issues with dripping, but it does send out a fine mist that leaves your garage floor an oily mess. And yes it does smell like a barn in your garage for about a week. The lanolin oil comes from sheering sheepI had 2 cans left after undercoating my truck

This is the best option for rust prevention in my opinion. Goes on easy and lasts!
