"I would never be happy with that mylar unless I had some way of shrinking it or mechanically tensioning it. "
Sorry, I meant that my 24" wide sample is not rigged with bracing in a way to tension the mylar with heat. The wing will certainly be tensioned with heat and flat, not as per my sample image.
OK, so about paint. I definitely will use floetrol. What I have trouble envisioning is an automotive smooth finish coming out of housepaint, i.e. that the prob can blow bugs/debris into and can be cleaned. Mind you, my last contact with gloss housepaint may have been 15 yrs ago, even then it was only semi-gloss.
I anticipate some tests in the coming week with advise from here, and see where it goes. Another route is spar urethane... I really like polyurethane as is used on indoors furniture, but it is too rigid for this, I hear spar urethane is tolerable, but I kinda want the entire aircraft to be white, clear, with black accents for air traffic visibility. A clearcoated LE is kinda retro, but function over form.
