I have read and watched a video from Tap Plastics, that says after an acrylic edge is either flame polished or buff polished it should not be glued with acrylic cement as it will craze. Are you guys that are flame polishing adhering to this practice? What about using the buffing method, same thing? I am trying to make sense of this, if you flame polish an edge and then need to glue it to another piece, what do you do?
