Why did both by my fog lamps crack a day after veil install?

[iflooru]

Applied some Veil G4 to my 2007 Chrysler 300C SRT8 on Friday evening in my garage. Temperature was in the 70's, headlights and fog/driving lights were at same temperature. Did a good job and was happy with the results. Drove the car to work 18 hours later and then home 6 hours after that with the headlights and fogs on. I have an 8 minute commute. Parked car in garage until today, Sunday, when I took it out to wash the wheels before church. I noticed that both fog lens are heavily cracked, not just little spider webs but cracks. Headlights and side markers are still fine at this point. I am running the stock 42 watt 2145 bulbs in the fogs and HID's in the headlights. There were no significant temperature differences or moisture and I didn't use any stringent cleaning materials prior to application. What did I do, or not do that would make BOTH lens crack the following day? All I can think of possibly is the film trapped/reflected heat in the lens and even after just 8 minutes of use caused the lens to overheat and break. This shouldn't happen. I could see if I were running higher wattage bulbs, or if just one cracked but these are only 42watts and they are OE bulbs. Replacement fog lamp assemblies are not that expensive but I am worried about the headlamp lenses after an extended multiple hour drive. I know HID's run cooler but I live in the sticks so I use the high beams often and they are not HID. Should I remove the Veil from the headlights, suggestions?

Thank you for hosting my pics.

Damn, those are large cracks... Maybe the film trapped heat, and some cold water hit them?

My cracks were only spider cracks, though there is a possibility that I may have already had those, and the Veil served to "highlight" them. Not really the case here...

Would you send me some close up PICs of those lamps?...I'd like to take a look at them. Please PM me with your direct email address and I will send you an email that you can reply and attach them to. Also, please provide some contact information in that reply as well as your city as I might want to get a closer look at them.

FINALLY someone actually has pics to back up their complaint! I'm sick of the people who come here whining about something, but don't think it's important enough to give us pics of it.

The crack in the first 2 pictures apears to have been there or happened when the veil was still wet. It looks to have veil soaked into the crack in both pictures. A closer examination in person would tell. Got to get back to watching CSI.

The first two pics are of the driver's side the other is the passengers. As I said I applied the veil in my garage in the evening and it sat til the next day. My car had been in garage for a couple hours before I applied the veil so lamps were at same temp as surroundings. No moisture or water has seen those lamps since it was applied. I'm trying to remember but knowing how anal I am I'm assuming I checked out the lights before I went to work the next day, but then again you actually need to crouch down and get close to notice the cracks. I offered veil guy to send him these for inspection when I get new ones installed.

As Stealth Stalker just said, I believe you are the first individual that has backed up a claim with something that we can actually work with, to try to determine exactly what is going on here...as we are very interested in determining the actual mechanism or cause.
