I bought a small enclosed trailer... 1993 vintage or so... from a friend who is getting out of re-enacting. Anyrate, she had sticky tranfer logos on the side for her group & I've been happily removing them with a heat gun... my cheapo Harbor Freight heat gun.
I've done a few heat shrink tubing on electrical connectors... and more time with the extensive decal removal. Very little actual use. The switch has broken. Mid-use, I shut it off & put it on the (trailer) fender to peel the softened decal. Picked it back up & switch no workee. Piece of Shut.
After the decals are removed, a quick wash with Acetone removes the glue & there's barely a shaddow of the old lettering... and I'm ok with that. It's part of it's history. But for now, I'm stuck.
