I've heard fuel (gasoline) does a job on lexan from people who

windshields out of it with the fuel tank in front.

I don't think so.  What's-his-name down in Texas ('Archer' is it?)

has

been making lexan fuel sight gages for the canards for years, and

they

work great.

Hi, Paul....that would probably be Vance Atkinson's fuel site gauges. I
installed them in my LongEZ, and now in my SQ2000....they seem to be
unaffected by fuel, and remain clear after many years of use.  Paul

Hi, Paul and Hurant:   In Feb of 2001 Vance Atkinson posted an email to the
Canard Aviator's Mailing List.(I hope he doesn't mind me quoting him)  "
...in the early years I made a half round bubble that was Lexan. It was
tough, but as some of the homebuilders put auto gas in it, they found out
some of the additives (that the oil companies deny putting in auto gas) will
attack the lexan, and I mean right now."  Vance now uses PETG (Polyethylene
Terephtalate Glycol)  which he said in his email was "impervious to most
things and is reasonably strong".

I have attached some pictures of the site gauges I have made for my UnCozy
from PETG compared to the normal Cozy site gages and the jig I used to make
them (the horizontal ones - one was too hot the other too cold - note the
acrylic bubbled when heated) .  The back plate is the same as Vance provides
made from Acrylic (Polymethylmethacrylate).   I'll be happy to provide
details.
