I know I've seen some posts from inmates who do vinyl (sp) transfer & sign work. Here's my question....I've got a cargo hauler that is lettered for business and I have been taking the lettering off so I can sell it (the trailer, not the lettering). It has navy blue lettering on white and I was able to strip virtually all of it off in under an hour....no sweat. My actual business logo is the same blue over a silver/gray background (NON-reflective) and that part doesn't want to come off for crap. I have MAYBE a third of it off after many hours of toil. Have been using a heat gun and that worked great on everything but the silver. It appears to be a different type of vinyl since any that does come off leaves no trace residue and the finish underneath is like day-one original. Any words of advice??? At the pace it's going, it feels akin to scrubbing a basketball court with a toothbrush. Any help would be appreciated.
