With this method DON'T thin the zpoxy. I know others have had good results but everytime I thinned the resin, it cured rubbery. Thinning works but the climate in your given area affects the curing plus the thinning agent has to be able to evaporate from the resin before it cures or it stays in forever...
Nice wing! P47?
What you say about thinners is oh so true, and it applies to paint finishes too.
I have a little roller that's meant for sealing the join in wallpaper (somehow). It's great for rolling down the glass and squidging the resin through the weave.
I also have a big resin roller for stippling. It's never worked, even on big jobs like my boat. But I can't bring myself to bin it!
