So far, so good with the spectar. Much better than acrylic... Spectar has been able to take pretty much all of the shapes I've tried. I haven't been let down yet. But I will say it is a little more 'rubbery' than I thought it would be. I expected more of a flimsy material when heated. That is no problem though. I've played around with sanding for a frosted appearance... looking good - and also with extreme heat to gain a slick edge. I've found that unless the edge is already pretty smooth, you're going to damage the plastic with these torches. The ends need to look pretty nice already.
