Windshield Repair Forum

Hi I went back and read old posts on this. There was a mention of an artical writen about how to detect this and how to deal with it. Does anyone have a link to this or can it be reposted? I couldnt find it. I curious about this as I have had some repairs where the pit filler dosn't stick to the surrounding areas. It seems to stick and fill the pit, but wants to just peel of the glass. I figure there must be something on the glass. Do you use any techniques to detect this before doing a repair? Do you do it every time? Thanks guys!

I have come across this and I usualy clean around the break with some acetone ( yes I know this can soften the pvb ) and have found it cures the problem.

This can also happen if the pit finish is out of date or a bad batch.

You can just put some acetone on a rag and clean the work area, this way there is no chance of it getting into the break.

You can also use Cerium Oxide paste or even pit polish to clean around the break too.

Try this: When you get one where the resin isn't sticking to the glass, put some crack resin on a piece of paper towel and rub it on the glass around the pit - really rub it like you mean it. At first it will look like you're spreading grease on the glass, but keep going and then switch to dry paper towel and the glass will be shiny where you've rubbed it. Only do this after you've cured the resin in the cracks or you might burp some air back in.

If this works for anybody, please respond with your results.

That is funny JTWindow!!!

I have never heard anyone else mention that, but your method is EXACTLY what I have been doing for many years!!! (sometimes I just use the pit resin.)

I discovered it by accident when I got frustrated with a pit that just wouldn't stick and i was REALLY gonna show that pit a thing or two. Low and behold, the darn thing stuck. Have been doing it ever since!

Putting other contaminates in the repair area is not appealing to me.

I picked up this trick from the times the pit resin didn't stick at first but did stick the second or third time. It looked like the resin was pulling the rain-x or whatever off the glass.
