Anyone using Rowmark Frosted Acrylics?

[John Noell]

Has anyone else tried the frosted acrylic (e.g, ice blue) from Rowmark? I just got some and it cuts okay but it seems to take a LOT to raster and reverse engraving is way too fuzzy looking. I'm curious what other people do with it.
PS If anyone needs coconut shell samples PM me. I also have some Fiji hardwood samples (mahogany, yaka) that engrave pretty nicely.
