I just found this ad and was wondering if anyone had tried it?
It looks to be just be an acrylic clear coat like you can buy anywhere paint is sold. Just with a “for 3D stuff” marketing technique. UV protection is common in acrylic clear coats too, which is what they are talking about I am sure.
Looks like some kind of resin. I’ve used some Smoothon products and they are very good. My son has almost finished printing a full size Halo helmet and wants to try this with some bronze powder.
I will let you know how he gets on.
