Large chip

Filling a pit with resin first to make your damaged area smaller and workable is like sculpters do working with clay, fill in where necessessary. Depends what you find out is best for you, drill in the pit or create a small bullseye next to the pit to start filling from there , as long you succeed repairing the dammaged windshield to the customers satisfaction and yours too, ofcourse !
There are many roads that lead to Rome !!

Please ensure you DONT drill the laminate. If there is one thing that will expose you to a major law suit when an occupant is ejected from the vehicle or vice versa, through a weakness you have made in the laminate, this is it. Any knowledgeable trainer should be impressing this on you from the very start. The Novus kit has a large pit adaptor which may be commercially available from other companies by now. Stick around and mop up the wealth of expertise that is available to you on this forum.

You're kidding, right? A tiny drill hole in the laminate would screw up the repair but it darn sure wouldn't result in someone being ejected THROUGH a windshield! That pvb layer is some incredibly strong stuff and a drill hole would not create an area weak enough to fail to a point of a body going through it! A lawsuit based on that wouldn't hold up.

Sorry I disagree> Any tiny imperfection in the PVB when stressed will be the point at which it will fail in the same way a screen cracks out from a chip. We had long discussions with the manufacturers of PVB when setting the British Standards on this point. I cant stress this point enough its very serious.
