treerun

I had StonGard installed all over my AR about a year ago by a outfit thats a good 100 miles from me. It's developed a few little spots where it's delaminated from (nothing too serious). I know that the installers use heat guns to "troubleshoot" StonGard, so I'm wondering if anyone here has either installed thier own or messed around with it once it's installed, and if so they'd offer some advice.
