pit filler problems

[gself]

I have started having problems with my repairs, I do a perfect repair but when i come back to the same car a few weeks later the pit filler is starting to lift around the edges of the repair, i have been going for about 1 year and have only just noticed this problem in the last few months.

Does anyone have any ideas what could be causing this, i only use GT resins.

Thanks in advance,

Gary

Great Question. This can be caused by a lot of variables. It can happen with any resin from any manufacturer. This can happen if their is any of the following on the surface of the glass:

Rain X/ other Hydrophobic treatments
Waxes
soaps/ and other detergents

The solution is to use Glass Technology's X-Phobic product before you repair the break. This will remove all of these chemical bonds that prevent resin from forming a strong bond. Finally a pre-treatment for windshield breaks!

Yes i can understand rain x etc causing some problems but almost every repair is starting to do this. I can't imagine being that unlucky with every windshield being contaminated.

HI, I see this every now and then. couple of questions. how old is the resin? what was the temp when you did the repairs? did you use the uv lamp? If you think you have on of the glass treatments, first clean with fingernail polish remover, or MEK. (Be careful do not spill on paint.) use a IR heat tool to dry out repaair, then do repair. When repair is finished clean old resin from pit area with paper towel and then add your pit filler resin. get back to me if you have any questions. JAinNH

Could be the heat, it quite often gets over 100 degrees here, problem is you can't just not go to work when its hot or you would go broke.

Try using other manufacture's pit resin and see how they work for you. You could start first by asking for samples of them

I have tried other resins but have found glass tech resins to be far superior to anything else.

Are you scoring the damaged area with the drill bit so the filler has something to key to? I have found that some repairs I have done have lifted but only slightly, if you score the damaged 'shell' area it seems to minimize the problem.
