I seem to recollect that one or an Auto Glass R&R business can buff out pits and other imperfections; as long as it's not too deep or bad !! I've seen a TV commercial of late by a company called Safelite. I'm not sure if those are in Canada ,but they show a device applying a clear resin :
The Windshield Repair Process.. Safelite AutoGlass - Windshield Repair Guide
The resin that fills and seals the damaged area is applied using an injector on the exclusive Glass Medic repair system. There's a little 7 step pictorial.Also, A quality windshield repair will restore the structural integrity of the windshield, help prevent the damage from spreading, and make the blemish much less noticeable, without removing and replacing the glass. Here's more info that may be of some help :
Effects of Stress on Windshield Chips and Cracks
As the auto glass experts, it is our job to conduct and share industry-leading research to understand how glass damage could impact you. In a recent
windshield damage study, we learned that stressors like extreme temperatures, driving and fatigue will cause existing windshield chips and cracks to spread quickly.
Cold weather stress
In cold weather conditions, windshields will develop a more concave shape. As a result, windshield chips and dings are more likely to spread in a horizontal fashion. According to a study conducted by the
Motor Industry Research Association (MIRA), chips were likely to spread more than 80 percent of the time at temperatures of 14 degrees (-10° C). Those tested at 32 degrees were nearly 60 percent likely to crack.
Warm weather stress
Warm weather conditions cause windshields chips to spread more vertically. The same study conducted by MIRA suggested that the heat itself distorts the shape of the windshield glass, which can lead to cracking by itself. However, it was also found that the cooling effect of the air conditioning unit is likely to set off a crack.
Driving and fatigue stress
Driving over a speed bump, pothole or other uneven terrain can cause a chip to crack. The force radiates through the car and puts additional pressure on the edges of the chip, which can quickly lead to a crack.
Although it is not possible to suggest how long it will take for a chip to spread, the study suggests that stressors like weather changes and simple driving will eventually cause or lengthen a windshield crack.
Getting a
windshield repair early can stop the damage from spreading and prevent the need for a windshield replacement !!! Hey, I just found a product that might be just what you're looking for [says it's $25.00 for a tiny 1OZ. bottle
