Remember to check your supplies, people. Duct tape was not designed to sit on a shelf for 10 years.
But the glue residue will stick to your gel coat for longer than that.
WD-40 (which should be a part of any survival kit, along with some PB Blaster) is pretty good for removing that residue. It also makes the surface nice and shiny, to look better than anything in the doomsday neighborhood.
Does WD-40 hurt the gel coat? I have some tape glue on my new lift keel that I need to get off. Anyone try those products like "goo-off" and such?
The gel coat on your Mac26X is so thin, I would be wary to use anything stronger than kind words of encouragement to remove the residue.
