B’laster Surface Shield Rust & Corrosion Protectant Spray, 12 oz — Up to 2-Year Protection, Lanolin-Based, Moisture-Wicking Formula for Metal, Tools, Equipment & Vehicles

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.

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.

simple, very easy to use. would have been nice to have had the straw for pinpointing the spray pattern.

this stuff works great on steel or iron that you want to protect From rust or where you cleaned an already rusted surface. tools are the %231 reason I use this stuff. I spend a lot of money on my tools. this prolongs the life of your tools.

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.

It's like having a vehicle in AZ YOUR car will last years longer structurally

It was easy to apply, good amount in a can, I ended up using just half of what I bought (3 for one car). I am going to buy another bottle and do a second car. I hear this stuff is exactly what they use in a shop and it lasts a year.

works very well and starts to work from inside the metal and stops the rusting process. a must have for any vehicle, i had to order more it works so well

have folding headrests and this works!!!

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.
