I don't know how well this stuff works but it is fairly expensive and I am not sure it would be worth the hassle.
I have a can each of an ISO free "urethane type" primer like PPG NCP, a can of REAL epoxy primer and a can of REAL urethane clear in a aerosol cans at home from Rubberseal "Medallion". I haven't tried them yet but there they are in the flesh in my garage.
