Excellent product. It is the best way to prevent rust on trailers and cars. Check out the in-depth youtube video on Surface Shield by Repair Geek. He did extensive testing.

Excellent Product. Just make sure you do not spray in Your Garage or areas that You do jot want to Clean after yourself. I use a self carwash location.

GOOD PRODUCT...USING IT SEVERAL YRS NOW. EASY WAY TO PROVIDE SOME ANTI-RUST PROTECTION %26 LUBRICATION TO MULTIPLE HOME %26 AUTO ITEMS FOR EXTENDED PERIODS VS 1 TIME SPRAY ALTERNATIVES.

Use this on your cars undercarriage/frame and components and you won't have to worry about rust. Sprays on easy, will seep down into tight spots to protect it from the salt on the roads. Plus repels water/mud really good as well. For the price it's hard to beat. Love the fact that it is clear.

It's rust preventative. I won't know for sure for years but everyone says it's good stuff. So far, I pushed the button and it came! What's not to like?

Being from the Midwest, using this is a must. Goes on easy with spray and one can will cover about half the underside of a sedan. Depends how heavy it is sprayed. Have been using for years and find it lasts about a year before needing another application. Recommend wearing gloves and some eye protection.

Brilliant product. Use this all the time to coat the underneath of my vehicles, protect them from salt, water, rust. Brilliant corrosion inhibitor.

pretty easy just had a little specks of rust so filed around them put rubbing alcohol let it dry and spray it so good so far

I only recently discovered this stuff. Works very well overall. It removes excess surface rust and debris and protects the surface underneath. Used it on my tractor and some underside suspension components on my car. Just spray on and leave it, wipe off only if needed, and it does it's thing well. Note that this is a surface protectant. If you need penetrating oil to unfreeze and/or lubricate rusted parts, you need to apply a separate product for that.

While this product may be very good for stopping rust, it did not meet my need. The product when sprayed leaves a thick layer of oil over the rust. I have a wagon that is beginning to rust in the wagon bed. After spraying the Blast product, the kids could not ride in the wagon. I will try to find another product.
