I have a GF basic and use 600 speed, full power, and a LPI of 340. It is important to do a thin coat, just to cover the material. I use a heat gun to help it cure a little quicker as well, with light touches.
You can easily brush off the laserbond before zapping with your fingers so be careful where you touch. After complete, i hit it with some water and the “non-zapped” laserbond comes right off.
When done, laserbond has a smooth finish to it, almost as it is barely there. I did find with using Cermark, while more expensive, leaves a raised embossed feel to it that my customers preferred.
