Customer wants led sign etched on both sides with a black background. So I figure I'll paint it black and etch off the paint to show the back etching and the front etching should show up fine. But the question I have is. I'm going to plot and mask the back and sand blast it and I'm worried I'll pull the paint when removing the mask. Should I blast the whole thing before I paint it to give tooth for the paint to stick. common sense tells me I should. I was gonna use lacquer and didn't know if they would chemically bond. Thanks Troy

Just use black vinyl for the mask and then you weed , blast and you have your black background

Yep that's how I should do it. Got a 80yard roll right here..... sometimes things are hard to see when there right in front of you. Lol Thanks
