I am told that the UHMW, (the white slicky plastic), machines well. but how quickly does it dull planer and jointer knives? Is it sandable? I have no experience with this stuff and would llike to here from those that do.

Have noticed no adverse effects on my planer or joiner knives, but cupping does occur in the planer process if you try to strip off to much material at one time. Sands well. I use poly glue & SCREWS because this stuff does not bond well at all. I purchased a special two part glue from a marine dealer, "liquid marinetex" but have not tried to use it yet. Anxious to read other responses to your question.

UHMW machines similar to wood and is easy on the tools. In addtion to what has been said, thin pieces(less than 1') need to be supported or they will curve(warp ?) a great deal. HD polyethylene is cheaper and works about as good. I have used super glue as well as epoxy to adhere polyethylene. Good luck.
