BlasterSurface Shield Complete Corrosion Protection for Long Lasting Automotive Rust Inhibiting Undercoating Applications, 12 oz Aerosol Can, Pack of 6 Spray Cans (16-SS)

I used to use fluid film for undercoating my vehicles in the winter time then I tried this. this seems to stay on the vehicles a lot longer doesn't seem to wash off is easy

Good overall experience.

Surface shield is as good or better than most. Could charge cans a bit more with propellant to be sure can is empty.

I believe the B'Laster surface shield to be probably the best anti-rust product available at this time. Other products of this nature are also good but B'Laster is a bit better. It is thicker and there is less drip off. Which should help it last longer. I typically give the vehicles a good coating in the areas where rust has a higher tendency to develop. Living in a "salt" state I feel this is needed to help reduce the corrosion. I have been using a similar lanolin product which has been very good also. I decided to give this newer product a try after watching a few videos which compared different corrosion protection products. My only complain would be that straws are not included. I was able to find a straw or 2 that fit in the spray nozzle. A straw is needed to get into areas such as the inside of the door panels and other tight areas. No straw cost one star. Would have been 5 if not for that.

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

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.

Truly an amazing product. It’s thick so be aware doesn’t drip off vehicle

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
