Any of you guys have experience in using this product? Some sorry bastard ran a key or something across the top of my hood about 15", scratching the paint down to the metal! Makes my stomach knot up just thinking about it right now, even worse having to look at it!! I swear you can't have anything nice these days. Anyhow, been checking out langka.com at their scratch and paint chip repair product and I'm seriuosly considering ordering it. Just wanted to know if anyone out there has used this stuff and if so how it worked out. Pleez lemme know!
