These things are JUNK waste on time and money. All they are good for is screwing up a windshield repair . Sure you may get lucky on a small percentage of breaks. but 95% of the time they will mess the repair up. WHY? three reasons off the top of my head
1. inferior low grade resin
2. no drill bit that, many repairs need to create an opening so the resin can flow in.
3. they cannot pull a proper vacuum to remove air from break.
From a consumer stand point I can see wanting to save some money. But I have been call out many times to try to re-repair a windshield chip repair that someone have screwed up with one of these DIY kits.
