By far the most amazing tool I own for removing pinstipes, stickers, seam sealer and underbody rustproofing�is a Snap On Crud Thug.
It uses a rubber wheel and that is what I recommend for pinstripes that are stickers.
3M makes them for drills and they are cost effective.
It also has stainless wheels that remove a 3/4" wide path, perfect for seams.

If your pinstripes are painted on, becareful.

Subject: best method/chemical/tool to remove very old pinstripe material

Fellow listees,

What best experience do you have removing the old pinstriping? Goo Gone &
plastic scraper? Mineral Spirits? Razor blade? Rubber eraser wheel on drill?

Please give me your experience. Thanks.
