G10/Galorite build plates?

Hi all, is anyone using?

I have the original frosted build plate and I also go an epoxy resin plate but they aren’t what I really wanted.

I want ultra smooth build plate. I used to get that from the G10 build plates I made for my old printer.

I still have some sheets of those here by they are 30x30 way too small for the K2. And I can’t hold them with clips on the side of the bed.

Anyone using anything like that? I would love to hear how and what.
