I see in the other thread you are spraying Jet Black so I looked at it. I found their technical data sheet which you might find helpful. I'll be painting my car black too and have gotten my black from TCP also.

I will also be using their DTM epoxy primer. It comes in Black. I have been using it on motorcycle parts and it sticks like glue to bare metal.
