I used some PTFE tape to give my shell a rubber coat. It was material left-over from a waterfall I built. It's actually used to bond pond liner seams. It's SUPER STICKY!! I only ran a band around it for now, but intend on re-doing it to cover the entire case around the sides. I actually covered the skwishing window with the material, because A) It's very hard to cut straight/true and B) The material is very flexible and C) It keeps any dust/debris out of the mod. I'll post pics when the final run is complete
I have some of that tape from the pond build. The only thing is that tape is UGLY lol but yeah VERY tacky! Hubby thinks I should try some tool dip it also comes in colors, now this may be very workable, just need to wait till I get an extra shell to explore different options. You know I am now glad that the XL was not avaliable in the shiney silver, as I would have bought that one, and that one would have been really slick.
