We're having our enclosed trailer lettered today, and I'm thinking about doing the truck at a later time to match the trailer. My question is, if I sell the truck in a few years, how do I remove the residue from the lettering? Is it even possible to remove it all? I've seen alot of trucks running around that have had the lettering removed and you can still tell where the letters were. The truck and trailer are both white if that makes any difference. Thanks!
