Windshield Repair Forum

Hello,

I have been doing glass repair for a year now. I am currently using a very nice delta kit. I am using th B300 to do all of my repairs. I recently did a combination break that was about an inch wide, and an inch long. I found that it was very difficult to remove all the air from the break. I have a couple friends that are in glass repair, who have created there own systems/tools. They both use a big suction gun, and tube to remove the air. I have seen them fix some pretty big breaks. The results are flawless. They have told me that I will not be able to get the same results with the B300 due to the limited amount of sucton that it creates. I have shop, and brain stormed for some type of additions, or modification that can be made or used. I was woundering how you all are getting good results on large combination breaks with the B300, and its limited amount of suction. Please any advise, ideas will be greatly appreciated.

Thanks!!

Hello JBolton,

I understand what you are saying about your concern for not having a powerful vacuum. Let me asure you that you have purchased professional equipment and you will achieve professional results with Delta's equipment.

Sometimes it helps as you gain experience to understand the physical make up of damaged glass. The resin will fill the break, and therfore air will leave the break. You may have to use a few different procedures to make it happen, so here are a few things that I have success with...

1. Using your probe, flex the glass around the injector. Watch closely for resin or air movement. You should see the break clearing as the air (black spots) begin to be pushed out by the resin coming into the break.

If that doesn't work...

2. Using your probe, flex the break by inserting your probe down the throat of the injector. You may need to find a skinny probe to slip through the Delta injector. Again, watch for air/resin movement throughout the break.

If that doesn't work...

3. Use spot heat on the inside glass. This will temporarily swell the broken glass closed (choking off the resin supply). Then as the break cools, it contracts and draws resin into the break.

I have had great success with this process.
I hope this helps.

Welcome jbolton,

I would recommend calling for technical support. There's no reason you shouldn't be able to do an excellent repair on the break you describe.
