Great thread, thanks for all the advice... lots to accomplish still for me.. just finished my initial cut outs... Not too many hassles. No cracks or tears.A couple of small, wayward slices during scoring, but not bad enough to see. If anything, it was hard to see the score lines on some pieces. I did find the plastic to be extra thick in a few places and it required heavier snips to help cut some pieces. Only had 2 really thin places that my exacto knife slid all the way through without much effort... Both of those were on the kidney belt piece. Other than that, the plastic seems very durable and flexible. Even when scored it took some effort to break the scrap free. in addition to sandpaper, I will be purchasing a dremel and bits for the final clean-up and fitment. From everything I have read, it seems to be a good investment and a huge help if used correctly and patiently.
Onward...
