Hi Matt,
Good choice! Scratch-off was the easiest, most effective Plex repair
method I found when I tested them for Aviation Consumer and Kitplanes.
Micromesh seems good, but it's labor-intensive, and you have to keep the
plex wet to avoid burning the surface.
Glad it worked!
best,
Cory

canopy would be $640 + $250 shipping to California! Ack.

You just put some of the first paste on the sponge and buff it in with a
drill at 1200 RPM or less. Then you wash everything down good including the sponge
and windshield with warm water. Then you use the next finer paste and repeat
the process. Etc, etc, until you've used the 4th paste that is kind of
like car wax.

buy this repair kit. It works!
