Peeling off wasn't too hard - just a metal spatula thing to get the bulk off, then used citrus spray and a cabinet scraper (see 1st pic of bogging).  It didn't leave scrapes, but a lot of work went into bogging up big (ie: 10 - 12cm) areas of cabinet delamination, and rebuilding the corners where there were dings.

Car bog for the bulk, also knead it on the corners, and lots and lots of sanding.  Hit it with a coat of black paint and it shows up all the imperfections you missed!
