Guys your molds for pre -pregs made from : polyster resin, epoxy, vinylyster? or anything more? as i know polyster molds that lots of do they from polyster but that holds not more then 60 celcius.

up to what temperature holds?

I typically cook at 100C as this means the pre pregs I use will cure in 1-4 hours depending on which material I use. You can cook hotter but then the cure time really becomes too much to have it running all day! or night!
