Cold-Weather Repairs
by Dave Shores

The cold weather is back and we need to adjust our repair procedures accordingly. Since resin tends to thicken up when it comes in contact with cold glass, winter temperatures require us to use a thinner-viscosity resin. This also makes it difficult for resin to flow into tight breaks. It is a good idea to get the inside of the vehicle warm so the resin will flow better. If that is not possible, you can start the engine and turn on the heater.

Curing Repairs in Winter
If you use the sun to cure your repairs, you should consider using a quality ultraviolet (UV) curing lamp. At the National Windshield Repair Association (NWRA) convention a couple of years ago, there was a presentation on this subject. In that presentation, the speaker said the UV-ray output of the sun was recorded each day for the entire month of November. There were only two days where there was enough UV in the correct range to cure the resin properly during the entire month. On those two days there was only a 15-minute window around midday when the sun could be used. I would suggest that you use a curing lamp on all repairs, no matter what time of the year. That way you are sure your repair is cured completely when you leave the jobsite. 

Moisture Revisited
Moisture is also more of a concern during the fall and winter months. Refer to Walt Gormanís article in the last issue of AGRR (see the September/October 2001 issue of AGRR, page 38) for information on how to determine if there is moisture in a break as well as to how to remove it.

Helping Customers Help Themselves
We need to remind our customers that they should not use things like pop cans, beer bottles and metal objects to remove the frost from their windshields. Every winter we run into damage that is caused by these items when the customers call us to remove the scratches they have created. I donít mind making some easy money by doing the scratch removal, but the damage would not have been created if the customer had been better-educated about his windshield. 

Dress warm and enjoy the fact that the condition of our highway surfaces tend to deteriorate in these cold months. In some parts of the country that means there is more windshield damage for us to repair. In Oregon, our highway department uses cinders to improve traction on the snow-packed and icy highways. We thank the State of Oregon each and every winter for creating business for our technicians. I hope that you have a great winter.
