Build Your Own SLA/SLS

Hola, I want to make a custom flexvat. I want to print the parts in PLA (because I read that resin won't damage PLA), and I want to coat the PLA with a 2-part resin, like XTC-3d Smooth on, or a generic kind, to make it watertight and so that liquid won't escape.

Will the resin melt or dissolve the epoxy? Or will it hold?
If anybody knows another way to coat and seal the 3d prints that would be great!

Thanks again to this board for the help.

----PS. While I have a thread open, how does PET or PETG holdup against resin?

I made my vat out of carbon fiber/epoxy and it seems to be holding up fine

Thanks for the reply, did you coat all of the parts with epoxy or just use it to glue them together?

I molded dry carbon cloth in to the vat with epoxy so the entire surface is epoxy. That said all epoxies are different

Thanks for your advice
