Is there a solvent that will remove rattle can paint without damaging the plexy?

Gary, unless it is Latex, almost any paint contains some solvent(s)
that attack plexi. This means a spot is not just on the surface, but
has damaged the plastic below the surface. You may end up having
to remove more material than you like to get rid of the "spot"...

Hope that helps,
See ya, Dave

PS: Before touching a real canopy, grab some scrap plexi, and spray
a few spots with the offending paint. Then test removal...
