Removing logos from trailer side.

I have used the stripper wheel from auto parts store. It fit in the electric drill. I removed vinyl sign on cab doors.
Let us know what worked.
Good luck.

 

If using a heat gun, don't crank it all of the way up. Burning the stickers won't make it any easier, and will actually soften the paint beneath (making it easier to scrape THAT off WITH the sticker). Yup...made that mistake. Pressure washers work, too, but can take a while and leaves bits of sticker everywhere they may blow, which can make clean-up a pain if you're somewhere you can't just say "F-it" and leave 'em be. What worked best was a low setting on the heat gun with a plastic scraper...but I was only doing the doors when I switched companies.
