Anyone got a suggestion for what I can use to get dried on masking tape and its adhesive residue removed from some airplane windows?  This is on a Lake LA4 and I suspect the windows are polycarbonate.   Any help would be appreciated.  TIA

Probably not. The solvents in most cleaners, wax and gasoline will craze and whiten Lexan. Cast acrylic or the older plexiglass more likely. Guess plexiglass and do a small area in a corner. Then polish only up and down in parallel lines, to reduce flairing in sunlight.

 

 

Here is one that works on all of them so the danger is reduced.
