I was wondering if you guys had any preferences in regards to what brands of engine paint you guys use. I'm going with GM Corp. Blue. I don't really know if any brands are better than others, I just dont want it comming off any time soon.

Any brand will do, just make sure the outside of the block is completely free of any oil film before you prime and paint it.

i always use the ceramic stuff, i can't remember who its by at the moment.

OEM Paints brand is probably the best in a spray bomb but its $24.95 a can. Probably a little excessive if you are just using corporate blue or black.
