As I said, tint will keep the pieces mostly contained if it does shatter.Adding a clear or tinted film would not likely reduce the probability of the sunroof panel further cracking. However, the biggest risk of having a damaged sunroof panel is that the tempered glass might shatter into thousands of pieces without warning while the truck is being driven. This actually happens enough that I know people it has happened too. Adding the film may help hold most of the thousands of glass pieces together if the glass fails. The film will not stop it from failing, but having the sunroof glass fail with much of it stuck together on the film may be preferable to having thousands of pieces of sharp glass rain down on the driver while on the freeway. So while using the sealant without drilling may only reduce probability a little, adding the film will likely reduce severity a substantial amount.
I didn't say it would keep the damage from getting worse. The support I was referring to when I said it does offer some support really only applies to if the glass does shatter. It will help keep the glass in place under some circumstances. As I already mentioned, even slight pressure from the inside could cause that to shatter. Not sure I'd attempt to tint that panel. Just keep your inner cover closed until you can replace the glass.You can get the glass panel (using the part number you supplied earlier) for right at $185 and change shipped from BAM, at least that's what it would cost to ship to my home address. Shipping may be more or less, depending on where you live.I should be able to get the glass panel delivered for under $250. But I will check how much the dealership wants to do it. I might be pleasantly surprised. I don't expect the cost to warrant a $500 insurance deductible. But we will see.
