Just finished removing the flaps and removing the clear UHMD tape that had been on flaps for 8 years. 3 hours per flap of fairly hard work scraping with a pocket knife and using lots of MEK. Also used 3M auto finish tape and glue remover, but the MEK seems to soften it better. It did not remove the paint but did put many scratches in it. Sure seems like there should be a better product to use for antiscrap on the flaps. I ordered new tape from Vans, Not installed yet. the UHMD tape does yellow, no matter anyone tells you. It turned black in areas from the aluminum and got very yellow over the years.
I looked up the SS tape from McMaster, but it was over $35.00 per roll.
DO not use a heat gun to soften the tape, it will make the paint come off with the tape. Don't ask how I know that.
