I just got back from the International Sign association show down in Orlando and found a lot of great stuff. One item I thought people here would be interested in is a material called Precision Board. www.precisionboard.com
This is a polyurethane board that can be lasered. I just tested a piece I brought back and it looks great. i have attached a photo. i am still looking at settings but the bottom is about 1/8th" into the material. This material is completely waterproof and can be finished, machined, routed and painted. We make signs all the time from a competing brand but theirs cannot be lasered.
We also have samples of a new glow in the dark Rowmark I am testing as well as some other products.
I will update as I finish going through the back of stuff i came back with.
