If you paint contains Toluene, you might be dissolving the Lexan underneath.
It doesn’t appear that lexan and hydrocarbons solvents are very
compatible: <a

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>hi,<br>
<br>
after precision-drilling a number of Lexan panels for the sim, it was time to
paint...<br>
<br>
i used enamel paint, the type that smells of tolulene - often used in model
building.<br>
<br>
when the 2nd coat was applied, it wrinkled and crazed like nobody's business. i
applied the 2nd coat well after 24 hours under moderate humidity and perfect
temperature.<br>
<br>
i _think_ an interaction is caused with the 1st coat, which (probably) isn't
adhering to the Lexan very well. i'm painting the backside of the panels (they
are clear in the front), so sanding is not an option.<br>
<br>
the question: has anyone else had success painting lexan? i've had no problem
with plexiglass, but this seems a different beast altogether. <br>
<br>
next trip out, i'll get some laquer and try it on a throw-away piece.<br>
<br>
...back to making replacement panels :-(<br>
