I just got my canopy set from Ziroli for my 11* B-25 and thought I would share a tip I use to take the flashing off the bottom of my canopies.

I have struggled to remove the offensive extra material before by cutting it away with an exacto and every other way I can think of and to tell ya the truth I have ruined many a canopy that way. When I worked for the boat factory we had to remove the glass lip from the hulls and rails after they came out of the mold before we could work on them. what we did was held th grinder flat and ground down till the lip just fell off.

Same technique with the canopy. lay a square of sandpaper 18 works or even 100 grit garnet paper. then hold the top of your canopy like it was a sanding block and sand that sandpaper with it and after a few seconds you will see the bottom flashing begin to fall off. This is where i just break it off by hand then taking some 220 on a piece of balsa lightly sand the bottom of the canopy until all signs of the lip is gone.

this works great and leaves you with a nice straight edge to boot so give it a try with your next canopy or turret.
