Watery Repair?

Hello All Wizards of Windshields,
I have a question. I was working on a repair yesterday, it was a combonation break that was about quarter size. When it filled it filled real good and I thought it was going to be perfect, but after it cured it looked watery around the edges and distorted. I used glasweld pro vac and GT Resins. It was a 100 degree weather and the windshield was very hot, I was able to pull it into the shade. I tried to cool down the windshield by using the a/c and time. The windshield was still pretty warm.
Any help would be appreciated.
Oh and I did not use any thumb pressure on the repair so I don't think it was flowered.
Thanks in Advance:eusa_wall

Could have been to much injector stem pressure or too thin of a resin also.

Sounds like you had a daisy affect where the resin ran between the pcv layer
and the glass usually caused by to much presure

What they said. Heat will help cause the daisy effect under less pressure.

What kind of resin would be best to use in this situation, I used medium vescosity resin. Also what is the best way to cool down a windshield?:eusa_eh:
Thank You for your replys

GT medium viscosity resin is the right viscosity for the repair.

Your cool down method is also good. How hot was the glass? Could you rest your hand comfortably on the glass? If so heat wasn't the problem. It sounds like from yoour description of the repair that the windshield was really hot.
You may have just needed more time for the windshield to cool down.

to cool off the glass spray rubbing alcohol on a paper towl then go over the glass with it, it will take the heat right out :eusa_danc

Thanks for all the replys, I'm sure the watery look was due to the heat. I will definetly let the windshield cool down alot more. I'm just not used to working in 100+ temps.:cool:
