This almost ranks as an FAQ on the aviation homebuilders lists and if
I had a real good memory I could say with authority many find success
using methel alcohol.

Start at the bottom of the ladder of solvents and escalate 'til someone
wins.
My progression is:
Mineral spirits (aka paint thinner, tar & oil remover)
Toluene (AKA goof-off)
Lacquer thinner
Acetone
dynamite or nitric acid (joke)

I've got some old Lexan that still has the protective paper on it and last
weekend used a piece for a science project with my daughter.
The project, a simple solar oven, would have taken us about 1.5 hours to
build, but when I broke out a piece of the Lexan, I had the worst time
getting the adhesive off that was holding the protective paper. This took
3
hours, experimenting with soap, vinager, kroll oil, even acetone (small
scrape- ruined), and I finally gave up and used a window scraper which
ruined the surface. Worked ok for the oven, but wouldn't want my ports or
companionway boards to look like that!
I've had this stuff sitting around, waiting for a project, for more than
10
years in Florida heat and humidity.
I'd like to be able to use the rest and need advice on getting the
paper/adhesive off.
Thanks, MMC
