There's a place in Evansdale that I think does this - I know that they do beds, as they sprayed mine, but I'm pretty sure they'll spray whatever you want. I was really impressed by their quality and service, and they were quite a bit cheaper than LineX (no... I don't work for them, LOL).
It's related to the question at hand, I hope that's not too much of an advert.
Anyway - there's someone driving around Waterloo who has linered (I don't know by whom) his entire truck. I thought it looked pretty sweet.... for a Dodge.
