I know there have been several posts latly about this but here goes again. Ive had 2 shield start to crack while drying them out. The first was a large crack that I looked at a as traing job. The lot was cool with replacing it if I couldnt fill it so... I first put in Dryout solution from LR. I then started to heat the crack with a propain heat pen. After a min or so, it cracked out. It left me with the impression that the gas from the evaporating water/ dryout solution would have built preasure, and not being able to escape the crack caused it to crack out. The next one was using the deltas moisture evaporator. I was doing the 20 sec on thing when it also started to crack (just 2 inches) This time my observation was the glass was cool, and I may have not heated enough of the surounding glass and focused too much on the chip. Im thinking that just like cooling glass in the summer, purhaps I should put on the defrost to warm the glass before going to the moisture evaporator. Any Thoughts? This time of year the glass is getting colder and lots of dew in the mornings. Wow another learning curve! Any help or even those little things you do without thinking about them would be great. I feel like I will be seeing more and more wet ones. I guess that was one pro to the hot summer glass... they dryed out fast on their own!
Thanks
