If you've got it rust free and are gonna park it inside - I'd skip the uc. If you're gonna drive it in salt, might consider it, otherwise no. Might want to look for another mechanic... JUST kidding. Actually, maybe he's onto something - several of these trucks I've seen that had uc, I noticed when I peeled it's dry, rotted, mess off that there was rust underneath. Hmm. Ok, give that man a raise. Bottom line, I wouldn't undercoat it anyway.
