Windshield Repair Forum

Just finished reading the March/April issue of AGRR magazine. In the repair product news there is a nice little article on the Heat X-Changer. Too bad there is not a picture of the tool, instead they show a tech working inside a bubble dome! Bummer!!
Also, I am a strong believer in curing under pressure prior to releasing the injector from the repair. There is an excellent article regarding this process written by Rich Campfield. It's a bit technical, but I think he thoroughly explains the chemical reaction that takes place. By the way, I use GT products.

Not to sound bias or anything but I think the Dr. Column articles by Korey were very informational and helpful to all windshield repair technicians regardless of your equipment preference.

As the disclaimer at the end of the article states, Mr. Campfield's "opinions" are solely his own. I never cure under pressure and after working with engineers and chemists for 15 years or so I disagree with just about everything he said in the article. We call curing under pressure cheating, as you can get a break that is not completely filled with resin to look pretty good if you cure under pressure, but I don't know why anyone would want to cure a break that was not completely filled. I'm not saying that is why you and others cure under pressure, but I just can't imagine any other reason to do it. My repairs look great and I don't have a problem with failures, so there is no point in spending the extra time to cure twice and tie up my light longer than necessary. We've had some pretty heated discussions on this topic in the past on this board, so I guess we'll just have to agree to disagree on this one.

Many experienced old-timers, inluding myself, were trained and told to cure under pressure.
My training was with GlasWeld >and they've trained and told many, many people to cure under pressure.

But when experience over time showed that it is better not to, and when the data are backed by research, we should be open minded and willing to change procedures.
Note: I am not sure what they are telling their customers today.

Same here, under pressure. Pre-cure as you are cleaning your injector, then pit fill.
