I'm just starting out with using 1/8" plywood for fins, and am wondering what is an easy and lightweight way to fill in any grain before priming? Normally with balsa fins, I use Bondo Glazing putty, sand, prime, fix any defects, reprime, etc. Then sand with some 800 grit right before painting.
Also, are the edges handled any differently than with balsa? I normally use the same Bondo glazing putty to fill in the grain and sand.
