This shows carbon fiber veil doped on. Process - Sand balsa with 320. Apply two coats Nitrate dope thinned 30%. Sand lightly with 600 grit sandpaper. Dope down the CF Veil with the same mixture and applytwocoats of this dope.
Sand lightly again with 600 grit.
Pour some full strength nitrate dope in a container and add as much talcum that will stay suspended in the dope, shake well and let settle for 10 minutes. Then I brush this on and let dry over night. I put a heavy coat of this slurry on.
When this dries for a day, i start sanding with 400 grit and then finish with 600 grit.
I I vacuum off the piece and clean with Windex and a rag. Now you can use whatever color you choose.
