Stop in for a cup of coffee

Picked up a chip in the Fury's windshield on Wed:mad:Went straight to NAPA to get a repair kit, they had no idea what I was talking about :wtf: so I ordered one online by Permatex and this is the last time I'll bother trying to support that local business. Meanwhile I put a piece of tape over the spot to keep out dirt and moisture. Have any of you guys used one of those DIY products and had decent results? The damage is a M&M-sized chip with about a 1/3 inch crack and luckily it is near the base of the windshield so it isn't right in my sightline.
had a pro try on a dodge van I had. They offer no guarantee. When they injected it, it popped the glass into a spider 3 or 4 times larger. had i left it alone it would have passed inspection.
