anyone ever use this stuff?it looks good but i wounder how well it holds up.also it has a heat rating up to 500dg i wounder how well it stands up on a set of cylinders?

 

the Metalcast??? I used it some. I needs a special basecoat or needs to be used on a polished surface or chrome to get the "anodized" affect. It also shows any inperfection that is on the metal. It does scratch easy and is hard to repair a scratch. It doesn't hold up at all to chemicals either
