just zainoed my windshield on sunday, and got a nasty crack via a tiny rock chip yesterday! I'm not sure if the elastic properties fo zaino helped put stress on the windshield. Most likely it is just a coincidence, but if anyone else has had problems, please let me know.

 

i doubt that the zaino could cause that at all... no finish is that strong! if anything it would protect (although a very small amount of protection for glass).

 

uh no. i have about 20 coats of zaino on my windshield, and picked up a few chips this winter. no problem so far, just a wierd coincidence.

thanks...as soon as I get my new windshield today, I'll be sure to put more zaino on it as well
