Painting over Rustoleum primer

["Tom Rech" <tdrech@sbcglobal.net>]

I have many loose suspension parts from my BT7 project that were painted by
the PO with the typical reddish-brown or gray spray bomb primer.  I'm
assuming that it is Rustoleum enamel primer, but not 100% sure.  I would
like to paint many of these parts with a durable black paint that won't
flake off if I spray it over the Rustoleum primer.  Can anyone recommend a
good paint/process to use?  I don't want to remove the primer if I don't
have to, but will if it is necessary.
