Hey flyer
I know what you mean about the pinholeing. I've done one plane so far in Koverall and dope and had the same problem. All my application was with an HVLP spray. I felt I was having to put more paint on than necessary and still getting some pinholing. Everything came out great except for that and it's minor.

I read afterwards on RCU(sorry, didn't save the link) that wiping down the Koverall with solvent first helps remove something in the fabric manufacturing process that causes this. I will try this next time, probably alcohol, MEK or something, experimenting first.


After using Koverall, I'll never go back to Monokote.
