Is it "thin?" I.e. applied with a paint brush or is more of a paste? Where do you buy it?
The paint goes on with a foam applicator, it's thicker than your typical paint but not a paste. I buy mine on eBay - their Starter Kit is only about $20 and should be enough to do an average machine. Here's an example, but there are a lot of vendors selling it:

I haven't used it but I don't think it is a direct bondo replacement because of how strong it cures. I think it would be heck to try to sand to a smooth finish.
