So this is a long shot, as I've found nothing indicating it exists. But here is my issue:
I am engraving large complicated clear acrylic pieces that then need to be filled in with black so you can see everything that's etched. Currently I leave the protective poly cover on the acrylic and use it as a sort of "tape". I then spray paint it with a water based acrylics spray paint. After that I then have to peel every tiny pieces of the protective plastic off one at a time that take around 2.5 hours to do a 28"x18" piece. My question is, is there something that you can put over the acrylic that maybe gets melted into the etched area as you cut? Like I said I know it's a long shot but there are not many options out there to achieve the goal of my process.
I have tried to etch it without the protective plastic on and use both a acrylic paint stick and also just acrylic paint with a brush. Both have not generated quality finish on the part.
