Greetings - (Still) getting ready to glue my tip-up canopy to the frame on my -9A. I'm close! I've got great advice and encouragement from several of you off-line for which I am grateful, but I thought I'd throw this out there to the hive mind as I haven't seen it addressed anywhere...
I plan to use black Sikaflex primer on the underside of the aft edge of the canopy. This is the approximately aft two inches that rest on top of the roll bar. Only about 3/4 of an inch will actually be glued to the canopy frame in this area - the rest of the primer application is really just to have a consistent primer/black color on the underside of this aft edge. It will be visible from the top/outside of the canopy.
Question - if I rough up the underside of the canopy here to help with adhesion, will the roughness, i.e. tiny scratches, be visible from the top/outside of the canopy after I apply the Sika Aktivator and primer? Obviously I want the outside of the canopy to look shiny and black, and not be looking through the plexi to a scratched and cloudy surface.
Does the question make sense? Basically I don't want to rough up the aft 2 inches of the underside of the canopy until I know what it will look like from the top side after I apply the Sika. For those that went before - what did you do in this area and how did it turn out?
TIA for any guidance here.
