I just bought a new "old" trailer and it's got a large amount of decals on it, and I mean a lot, anybody know any "home brews" that will help get them off? I plan on starting on the smaller ones with a heat gun, but the whole front is covered with a big "flame checkered flag" that will take a long time with a heat gun, the decals are cracking, was going to try to get some off this weekend, and living where I do, I can't just run down the street and get something, any body got any ideas on a home brew that will soften them a bit but won't damage the paint?
