Thanks, Clive. Been researching this until I'm blue in the face (not pretty), including sundry websites and other sources. Until I get some feedback on the Krylon/Rustoleum coatings option -- which is only dealt with generically on the sites I have visited -- I'm kinda stuck. Mind you, with haulout (Ottawa, Canada) only a few weeks away, I've left my outer frames in place and the boat
will be covered through the winter, so I have time. I had considered Acrylic
but I have a curve to deal with and heating
and bending would have been a pain. Once the outer frame is removed, I plan to affix the Lexan
with 3M VHB tape and run a bead of Sikaflex 295 around the tiny gap left when the VHB is in place.
