Windshield Repair Forum

ever heard of anyone using a vibrating tool on the inside of the glass to help the filling process? This was a first for me. Had coffee with another tech who uses a vibrating soft rubber baby teething toy pressed against the backside of the damage. Seemed weird to me but he says it works.

Are you sure you guys having coffee?

And just what do you mean by that?

It would sound like it would work to make the resin move faster. I might have to give this a try.

He claimed that the rapid vibration combined with a slight pressure flex caused the resin to flow better.

Technicians have been using this procedure for years and some swear by it. It didn't seem to make any difference when I tried it, but then again I don't normally find it difficult to get breaks to fill. The idea does have some merit though, so for anyone who does struggle with filling a break it is certainly worth experimenting with.

The techs that I know who use this method use the little felt bullet points that are available for Dremel drills, which is what I used as well. In fact, I experimented with a number of different felt tipped wheels and spindles as well as a few soft plastic tipped tools that I modified to fit the drill, trying to create various levels of vibration and heat. However, I must confess that I never tried a baby toy, so maybe that's the secret.

What's up with your comment Grouselab?? What are you implying?

OK splitpit Kudos to you!
I have been punching star breaks in this practice windshield I have all week. To be honest I have been having trouble filling tight legs in them. I just ran out to the garage and tried your way...believe it or not I think it did work. I had this star with 8 legs....4 of which were very tight. I put the big felt pad on a 10.8v dremel and powered that thing up to about 5 (10 being the highest). While pressing in from the insdie part of the windshield I rolled the tip around the break. Surprisingly enough it filled those tight legs. I will try more tomorrow and post the findings.
Thanks so much for this tip!

Glad it was helpful to you! I'm going to do a little experimenting as well!

When I started out with another company they were teaching to use the battery end of a dremal to vibrate the glass... I tryed it and was not impressed...
Flexing does better for me..
