And if you can find someone to spray hot asphalt on your stuff go for it. never need to worry about that stuff coming off. Just cover your drive shaft and exhaust system. Easy way to to make your driveshaft out of balance or catch you exhaust on fire. Not good.

Gotta agree on asphalt. There's 32 year old black goop on the underside of my 1980 Buick and that undercarriage is in better shape than pretty much anything else I've seen around here. Even places where I rubbed some of it off while working on it have not had any rust since then.

What about when spraying it on you spraying over wires on the underneath is that good.

Not sure. Maybe if all your wiring is covered in loom or something. I would think that type of under coating wouldn't allow proper cooling if you over running them.

Fluid Film, I use it on everything. Undercoated a new truck over a year ago, absolutely no rust on anything.
