Fluid FilmStens 752-515 Rust and Corrosion Protection-11.75 oz. aerosol can, Multi

Nice undercoating, goes on easy (but it is somewhat messy so wear latex gloves when applying) and one can goes a long way plus, unlike other undercoating products, it don't stink, big plus in my book. I did my wife's Suburban with ONE can. Not bad at all. It will drip so be apprised of that and don't apply it in your garage or it will drip on your clean floor. I did mine outside in the gravel driveway. Gonna do my pickup truck next. 4 can pack will do every vehicle we own. I'm impressed.

Fluid Film really works and protects your vehicle and other steel items like garden equipment from rust. I have been coating my truck with this since purchasing in 2007. 300K miles and 17 years later in New England winters without any rust. The sprayer attachment is a bit messy but allows you to get inside frame rails and panels. Cheap insurance against early frame failure.

I spray the frame of my trucks twice a year with this product, it offers great protection and looks good but I wished it lasted longer

Works great but has a smell like an animal died inside the frame of your truck.

Works as good as the regular stuff just black and a little more money
