Randall,
During my years in aerospace R&D I used a lot of plexi and lexan for
prototypes, and used a heat gun (hair dryer couldn't get hot enough) to make
all sorts of smooth shapes. I'm sure you know to use gloves 'cause heat guns
get HOT! The plexi will have a longer shaping dwell time than lexan, but
lexan is sooo much stronger. Once you get the hang of it, it's a piece of
cake. Try practicing by making some picture frames first... that way you
won't ruin the deflectors right off. Having a form would make it that much
more fool proof. Good luck!
Brian

Since you've raised the topic, what is the easiest way for a total novice to
go about putting some mild bends in some 3/16" Plexiglas? I've got some old
AMCO wind deflectors for my project TR3, but the plexi is broken on one
side. The original had a gentle S-curve to fit around the car body better,
which I would like to duplicate for a replacement piece.
Is a heat gun the way to go? Are we talking hair dryer or heat shrink
tubing gun?
