OK, My brother told me about it. He worked at the Calgary south VW dealership and they offered it with a guaranty if you had it applied and you got a rock chip you got a new shield for free.
In the 3-5 years he worked there he only heard of one claim, guess it was a huge rock
I have had the med one on the ZR1 for 5 years and heard some twaps on it from rocks and nothing. I now put the Ultra on it this spring.
Seems like it works.
most glass places probably won't sell it because it is like losing you as a customer if they apply something that makes you not be a repeat customer.
Every Corvette windshield should have it on it...... and I don't sell it or make anything from it. I got a few guys it and hope it protects them.
Roger at Glassmasters on Argyll and 95 street ( Edmonton ) offers it.... Baby Ray had it done there, he is on the highway lots, he needs it. ( a few of us installing ourselves... not that hard to do - need a mister to wet mist shield in between coats )
No real deals on it....... $100 installed for Ultra, $75 cash n carry and also cheaper for the med version... do the Ultra for the Vette shields.. expensive ones.
