BlasterSurface Shield Complete Corrosion Protection for Long Lasting Automotive Undercoating Applications, 12 oz Aerosol, Pack of 6

I will definitely be buying again when I need to reapply. I put it on a year ago and there is absolutely no rust under my truck at all! It's protected exactly like it said and it's worth every penny. I think I used 6 can doing my crew cab truck. I pulled door panels, tailgate panels, and inner wheel wells. And sprayed everything I could reach. 100% recommend buying this!

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.

JUST RECEIVED MY 12 CANS, it takes that to do the whole underneath of my Silverado 1500, THIS STUFF WORKS AWESOME !! LAST APPLIED 2 YEARS AGO NOW IT'S TIME AGAIN TO REPLY, I MEAN WHERE CAN YOU GO FOR UNDER COATING FOR $100 THAT WORKS, HIGHLY RECOMMEND IT !!!!

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

I bought the six pack after looking for a good undercoat for rust prevention recommended from the Repair Geek YouTube channel. I bought the surface shield cans and the Amazon recommended extension wand. The wand leaked more product under the cap than the blaster factory cap, so I had to throw it away. It just doesn’t sit right or seal correctly. The other cans leaked from under the factory cap and covered my hands and driveway any way. They also clogged up occasionally. I’m going to try fluid film next bc no one seems to have issues with them or the extension wands. I did use a gallon of surface shield with my compressor sprayer and had no issues, but wanted the cans and longer thin wand for small areas hard to reach. Too bad, I really wanted the cans to work but they are junk. What a mess, look at some of the pics in other reviews that’s exactly what happens.***update on Fluid Film can*** I tried fluid film can and wand instead of the surface shield. The wand that came with FF leaks just as bad. I guess I’m staying away from cans on both products.
