Bill,
I have used a product called POR-15 which seems to do a good job.
It is a moisture-cured urethane resin which is designed to be painted
right over the rust (hence POR). It allegedly pulls the water out of
the rust crystals to aid in the curing process. You brush off the
loose rust, but don't grind down to clean metal. It cures to a very
hard finish, and can be painted over. Once it cures, it's impossible
to remove.
I have tried it for about a year on some exposed rusty metal (the
remaining shards of the rockers on my van), and it seems to be holding
up. It is available by mail from the manufacturer in NJ, but I don't
have the details with me at the moment. I'll post the address/phone in
a day or two. It's about $30 a pint, which sounds like a lot, but it
covers well. J.C. Whitney have a similar sounding product in their
catalog for about half that price (probably comes out of the same vat
at Dow or somewhere :^))
I would definitely recommend it for a frame, unless you're doing a
concours restoration. Epoxy paint sounds like a good idea too, but
I've never tried it. Anything waxy or oily will eventually evaporate
away, and will prevent you from painting anywhere near it.
