Any anti-corrosion system has a finite life. Even a galvanized frame will eventually rot after the zinc corrodes away. All paints have a finite lifetime, epoxy being a little better has a longer life. In any case once the protections' lifetime is exceeded you can expect the base metal to be unprotected. I have worked on all kinds of cars and many didn't have ANY protection! That makes any survivors even more valuable, most others have long since dissolved. Cars from the 60's and 70's are especailly bad, the metal got thinner and thinner and the protection got less and less. The disposable mentality, you traded the car in anyway after 3-5 years so who cared! One of the failings of epoxy is when it fails it seems to accelerate the corroison by trapping moisture against the metal when it cracks. Probably the "best" thing to do is remove all of the epoxy, replace any damaged metal, and hot-dip galvanize the frame. This would add some weight. Another idea would be to use a rust-inhibiting primer like POR-15. In any case since the lifetime of the epoxy is over the thing to do would be to remove it and replace it with something else. The frame is not the only thing susceptible to rust. Brake lines, hardware, the headlight boxes, brake cables, etc are all damaged by corrosion. The bottom line here is if you want your car to last a long time you won't drive it when the roads are salted. In the salt belt most people that drive fancy cars park them for the winter and use a "beater" for the winter months. The convertable (and the Delorean) is saved for the NICE weather.
