From what I have read, epoxy based fiberglass has a bond strength of about 2000 psi, while polyester has less then 500 psi...
Remember this is the "glue" strength to another surface, not the actual strength of the resin...

What about the exothermic reaction from the fiberglass resin setting melting or warping the plastic?
If you don't over do the catalyst, which most people do, you can avoid it.

I did this very project on my Boba Fett backplate. I indeed sanded the crap out of it.... every square inch of it and used an epoxy based fiberglass. I laid down 3 or 4 layers, not sure since it's been a good 5 years.
It has never ever had one area of lift since completion. The heat did not warp the plastic since I didn't over use the catalyst, which if done improperly would indeed heat the crap out of it enough to warp.
Go with confidence, but go easy on any catalyst you may use.:thumbsup
