Almost done with the wingtips! Tonight I riveted on the L wingtip rib, and also tested some paint that I'll use on the nav light lenses. I painted four different samples on some scraps of the Lexan material I cut the lenses from:
1. "Plastic" paint, un-scuffed surface.
2. "Plastic" paint, scuffed surface.
3. "Polycarbonate" paint, un-scuffed surface.
4. "Polycarbonate" paint, scuffed surface.
I bought both paints from a local hobby shop. I plan to subject both samples to some semi-scientific testing, subjecting them to high speed rain, cold, heat, and abrasion. The winner will get painted on the lenses.
I also cleaned up the lenses themselves with Plexis plastic polish. They look really good now.
THe second photo shows the two paint colors I tried: Steel Gray and Silver. Not sure which one I like better.
The third photo below show the way I painted the light cove so that there is ample surface area to bond the reflectors on. I will be removing the paint from the right wingtip in the same pattern.
