L285/L335 with microballoons was used by a large number of german and
polish manufacturers. Poles usually apply Aerodux and grind that down as a

primer to make the epoxy stick to the plexi. Alternatively, using a
polyesther
instead of an epoxy makes for a stronger joint but significantly shorter
potlife
(minutes not hours). I have seen various other modern kits used too. Some
with great succes.

After reading some RV builder sites, I'm thinking what was used on my

Pretty sure it is NOT Proseal. When that stuff cures, it is stuck. It

I was once told that 3M 5200 is great stuff, but I have not used it,

All the Austrias I've seen/owned/flown including an SHK, used screws to attach the canopy to the tubular steel frame.
Good Luck,
