RE: pt-19 finish
That's exactly the dichotomy between modelers and full scale builders/restorers. We sell to both and not once, never has a full scale builder ever wanted the fabric to show. If anything they go to the extreme for it NOT to show. In fact, there was a Stagerwing at Oshkosh where the finish tapes were not readily apparent even on close examination. When the secret was told, he had actually covered the plane again after it was stitched and never applied a finishing tape anywhere on the plane. The FAA was furious and made him Re-cover it correctly.
Anyhow, the fabric or weave should not show on any model and the pinked tapes should just be a hint that they are there. Most modelers over dramatize that it's fabric covered.
After thinking about it a little more, a PT-19 wing is plywood covered with light fabric. What weave is there is barely discernible on the wing. The control surfaces are fabric but you still can't see the weave of the fabric.
