Can a mirror be used instead of e.g. glass to get a good finish or will it be a problem with the epoxy?

I have infused a lot of smaller pieces of CF on an old mirror, glued ( with epoxy .. ) on top of a thick piece of plywood ..  Works fine ..

A sheet of thick plate glass is better, for the simple reason that you can check your infusion from the "finish side" through the glass ..

I mainly use "EC Easy-lease" on the glass ..

"Sapere Aude"... Dare to KNOW!

Do not adjust our mind, theres a fault in reality :-)
