Undercoating a Taco

Not sure, I believe it is petroleum (oil) based from what I could find online, I did undercoat and rust protection, I think it came out to $550 +tax. Yearly touch-up is like $50 (catch is need to do that to keep up their warranty. The rust protection they drill a bunch of holes in shit (didn't tell me that part before they did it), so be prepared for that. And take off your spare tire as they don't and will just spray around it (some other bs about a lawsuit in the past).

Overall I am happy with how its holding up though.

After they do it, inspect everything, had some on my seats, came off with a remover fluid they gave me. Also hit the driveshaft and I had to clean that off.
