I'm not new to the forum but it took me forever to figure out how to post something. I just bought a new truck and the dealer talked me into having the Simoniz glass coat system put on the exterior of the truck and also something simular for the interior. It cost me $329. And they said it's garanteed for 7 years. I got a bad feeling about this and afraid to ask. But here it goes... Does anyone think this was worth it?
