Epoxy can be thinned with lacquer thinner or acetone. I wouldn't do that in a structural situation without tech data from the manufacturer. As a pinhole filler, it shouldn't be a problem as long as you keep the amount of thinner to a relatively small amount (<10% for sure).

That said, I've found that as a pinhole filler, you can squeegee in normal epoxy - no need to thin it.

Thinner - - EEEEk

+1, I took a micro mix with fast hardener and used a hard rubber, sharp edged squeege, raked both directions to fill the holes. Let harden, only light sanding needed.

Then did the same with neat resin, slow hardener, and got all off that I could to seal but not have to spend any time resanding. Scuffed with red scotchbrite and primed.

The hard way is to lay on the resin thick and have to sand it back to smooth. Using a squeege avoids that. Some use a thin steel one, but that did not work for me with the small area and contours of the transition on the canopy.

I used Smooth Prime on the RV-10 as my Lancair IV neighbor swears by it. Never again. It more than doubled the work.

Carl,
I'll bet I know your Dogwood neighbor... he loves that Smooth Prime... but I agree with you...
Smooth prime is simple, and usually trouble free for inexperienced users, but it's not the most efficient product out there...
