Wing Tip Lens
FYI - Do not use a Sharpie to mark the cut lines in the wing tip light lenses. Isopropyl alcohol won?t remove them! Fortunately, ethanol will, with time and flooding. Took me twenty minutes to get rid of the marks.

I used grease pencil/china markers for layout on my plexi-glass.

Good idea. Now, if I could only find one . . . No luck at Staples, Walmart, Publix. I?ll try Home Depot next.

I use fineline flexible vinyl tape. It can be stretched to go around compound curves and it can be applied and removed and reapplied if you need to tweak it a bit.

It's been a couple of years, but I believe that I was able to remove sharpie marks with mineral spirits. MS are a preferred solvent for cleaning acrylic; I used it on the whole canopy to get rid of the adhesive from the covering.

Thanks for the suggestion, but I tried mineral spirits on the way to ethanol. It didn't work. My wife suggested hairspray, but she didn't have any for me to try.
I didn't have a problem with the first lens, but I guess I just got lucky and didn't have any marks in the middle of the lens that I needed to remove.
By-the-way, Home Depot has grease pencils. They call them China Markers. Not a very clean line, but they don't cause any damage and the marks are easy to remove. I may try the fine line tape if I ever have to do this again.
Thanks for the suggestions from everyone.

Suggestion - do NOT use Acetone to clean stray epoxy off of your wingtip lenses (or canopy, I expect).
Bad things happen.
