Windshield Repair Forum

Hi Gang,

I am still doing wsr part time, mixed in with my detail business. I have been very busy with detailing (thats good)! Have been doing 2 or 3 repairs a week.

Monday I did a repair on a pickup that I also had a detail to do. I started the repair then started to do the inside cleanup to save time.

The way the pu was parked the sun was shining in the back window and I was worryed about uv rays, then pop I had an idea! I put the Delta uv procetor with the suction cups on the inside of the glass! Worked Great! The repair filled faster than usuall so I may have had this happen before and didn't know it.

Autoglass filters out UV thats why you dont get a sunburn driving around, The laminate layer absorbs the majority so for the UV to kick off your resin from the back window it would have to go through two layers of laminate and 1 1/2 pieces of glass. It doesnt hurt to block the sun from inside but in actuality it doesnt do much good either.

"A car's windshield blocks about 85% of the sun's ultraviolet (UV) radiation. Other car windows block only about half. Heat waves pass through glass and get absorbed by our bodies. So, the sun's rays can heat us shining through a windshield.
Glass protects us, though, from the UV portion. It absorbs most of the UV like an exceptionally effective sunscreen. Good thing, too, because skin absorbs almost all the UV rays that reach it."

I'm not sure if the above is true or not, but whenever I'm driving with my hand on top of the steering wheel, I can still sense the heat radiating from the sun.

You have more to worry about from reflected and ambient UV than from what might filter through from the inside of the vehicle. This is especially true in the summertime when the sun is more intense. Take every precaution possible to prevent premature curing.
