Finally got tired of replacing the duct tape / aluminum foil shade on my back window.
I read the various posts on Plexiglas painting and it seemed like 2 part polyurethane would be best. Unfortunately, what I have read elsewhere is that it should only be sprayed while wearing a positive pressure respirator (which I don't have) and I didn't want to brush it on.
So, I used Rust-oleum "Plastic". I took a few pictures of the process and outcome. The white on the inside is duct tape residue which came right off with WD40:

Here is what I did:
-Masked off the area
-Sanded the surface with 600 grit sandpaper
-Cleaned with mineral spirits
-Dried well
-Put on 2 coats of black. 20 minutes between coats
-Put on 3 coats of white. 20 minutes between coats
-Let dry one hour then removed the masking
-Let it sit a week, flew yesterday
That is what I did and so far the paint is sticking. I'm not recommending this procedure until I see if its still sticking a year from now.
That last step is probably not necessary, but the can says its a week to full strength.
It blocks light well, but there are some slightly thin areas. Nothing that makes me want to do it over, but next time I'll go 3 coats of black and 4 coats of white.
The white is very reflective and was much cooler to the touch than my unpainted aluminum in the sun yesterday.
I wanted black on the inside to reduce reflections inside the cockpit. This works ok, but the black is a bit more glossy than I wanted. Next time I'll use 400 grit sandpaper (or bigger) so the black will be less glossy.
"Next time" is if this holds up for a while I'm going to do the top of the canopy and take off the Kruger shade. I'll probably do this next oil change if its working out.
