Those of you that have done the "Line-x" thing.???

[Ma\'Deuce]

I stopped in the local linex shop today and inquired about getting my grille coated. nice guy(kid)by the way. i asked for a price and told him it was a coated plastic grill, then i got a blank stare for a minute. he said they have some trouble with linex sticking to plastic. in particular, cromed plastic. even if he roughed it up, he said he wouldn't be able to warrenty it. anyone else have this discussion? he asked if i could get it primed first then he would have something pourus to stick/adhere to. i can see where he's coming from, but wondered about painted surfaces. he said plastic is what gives them problems, and paint on cars is actually a polymer right? i wanted to email Line-X corperate and ask the question and get a letter back maybe that i'd be able to take into him, but their site doesn't have a "contact us" button. any ideas? thanks.
