Has anyone used this All Metal Filler before?
I bought some at the local paint supply place today on my lunch hour, it is more expensive then the regular plastic body filler but I thought I would give it a try.
It is supposed to mix up and spread on similar to the other stuff and it says it can be sanded within 15 to 20 mins.

Anyone had any experience with it before?
Should I save my money and return it for the regular stuff?
