Take a look at Hammerite and see if that strikes your fancy. What I'm doing with my frame and several other parts is coating with POR-15 and topcoating the POR-15 with Hammerite...I have some other parts with a POR-15 base and POR-15 (not the same stuff, just the same manufacturer) chassiscoat topcoat.
Hammerite is awesome stuff; sold around here (Denver) at Home Depot; you can buy either spray cans or quarts; Castrol super clean (in purple bottles) works great for cleaning just about anything, including degreasing old junkyard parts.
