What's the best way to remove remove gum residue from tape I usaed to hold pieces together? Denatured alcohol?
Update from 2014 archive:
Following advice from John Harris, I used 120 sandpaper and laquer thinner with a scraper to finally remove all that sticky goop. (He advised against using soaps or mineral spirit as that might leave traces behind that prevent new epoxy layers from properly connecting to the existing epoxy.)
It still took quite a bit of rubbing, scraping and sanding until the surface felt clean again. In the future I will make sure to remove the tape *much* more quickly.
