Windshield Repair Forum

Some of you have mentioned drilling into the batwing when repairing. Are you referring to drilling into the point of impact or drilling actually into the batwing and then going through the vacuum and pressure cycles

I always drill and pop the point of impact I find this opens up the break allowing the resin to flow quicker, But I am sure someone out there will disagree so try it and do what works best for you.

We all should know that I'm not an expert yet!

However, I did do 3 very small batwings this week and zero drilling. One I couldn't even feel with my fingers going across the glass. I almost drilled but thought I should at least try first w/out drilling. Turned out really well.

Madmike one of the problems I find when not drilling first is that if you decide to do it later the resin acts as a lubricant making it harder to drill.

I would like to know why some people are against drilling and popping.

As far as I am concerned it speeds up the filling process without any undue cosmetic or strenght problems perhaps even Jeff would like to add a thought on this.

My deciding factors are glass temp and location, on a hot windshield I will pop as a last resort, also if the break is close to the edge I will pass.

It's all personal preference.

In Delta Kits' experience, all things being equal, a non drilled repair will look better than a drilled repair.

Of course there are breaks that must be drilled, but there are many people that go a bit overboard with the drill.

Look at it this way, the less you drill, the less you have to spend on drill burs!
