I have dabbled in MX panels (which use the same low energy panels) and using other manufacturers materials, and believe me I would only advise on either Convex or a material called Substance.
Both are equally good.
But as for doing full wraps onto low energy plastics I reckon you will always have issues as the material is so thick and their is a point to were you have to cut to release tension.
I hope you are not expecting to make any money in this venture as you say the material is very very expensive and by the time you have templated a machine and added time on for design their is very little (if any) profit to be made in this game.
Believe me I lost over $8,000 trying the cheaper options.
