Hey folks. I suspect that my answers can be found with some digging here but I thought I would simply ask the question. I'd like to experiment with doing up some "badges" for car lovers so I am looking for the plastics that I can laser for this purpose. Some I'd like to be able to mount outside with dbl-sided tape or epoxy and some I'd like to mount inside a window with tape, so they can be thinner and less rigid.

For the outside deals I am thinking of finding the thinnest acrylic I can; ~1/16?
For the inside, is Mylar safe and would it stand up to heat from the sun or would it warp?
What are other choices for rigid and semi-rigid?
I'm also looking for a clear laserable anti-scratch to use with keychains.

Could you guys give me a brief and simplistic view of laserable plastics that I can run with? We have Regal Plastics here in the Dallas area that I am going to phone on Monday but I'd like to be a little bit prepared so I dont get into the wrong stuff again.

When is Sawmill going to activate their community wiki? I'll bet I could find this in there pretty easily...
