Does anyone have experience using micromesh or similar products to
remove fine scratches from glider canopies?

Hi John,

To date I've done a 2-33 canopy and part of my LS8 canopy. The stuff
works great, but I would caution you to really pay attention to the
sanding patterns in order to keep the original optical quality if
you're just doing a spot repair. When I fixed a big stratch in my LS8
canopy (inside), I removed the scratch just fine. But, I made the
transitions between grits a little abrupt. The result was that I
created a small wave in the canopy. It's not bad, but it is apparent
when I move my scan across that spot. A one inch scratch will
require probably a one foot working area as you expand through the
grits. I made the mistake of trying to contain the area by masking
off the area in expanding squares for each pass. That resulted in
sharp "edges" at each grit. Better to to have more freedom to
feather up through the layers. I know better than this from wing and
auto body repair, but it "seemed like a good idea" at the time :-)

I concur with P3. There are no shortcuts to polishing out scratches
properly, dont even think of using power tools to speed the process
up!
Copious amounts of clean water, a slowly running hose is good and
attention to the directions is the only way to get a good result.
