[simpits-tech] CRAZEy Lexan

[Joseph Fagner]

Oh, another thing I just thought of.  If you paint contains Toluene, you
might be dissolving the Lexan underneath.  It doesn't appear that lexan and
hydrocarbons solvents are very compatible:

hi,

after precision-drilling a number of Lexan panels for the sim, it was time
to paint...

i used enamel paint, the type that smells of tolulene - often used in model
building.

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.

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.

the question: has anyone else had success painting lexan? i've had no
problem with plexiglass, but this seems a different beast altogether. 

next trip out, i'll get some laquer and try it on a throw-away piece.

...back to making replacement panels :-(
