John -
The key areas are, IMHO, the inner rockers, quarter panels
where the sheet metal is spot welded to the inner quarters, trunk floor, floor
boards, eyebrows and lower rear quarters. All areas except inner rockers
are accessible, so I would seal those areas with POR-15. I used to use
Corroless, which was sold by Eastwood, since it did not contain isocyanates. But the Eastwood
stuff is now a different formulation since Corroless is no longer available, at
least in this country. The new stuff is
junk. No better than a can of rustoleum. If you don't want everything to be the
POR-15 color, such as the inside of the trunk, you can spray over the POR-15
with what ever color you want when it gets tacky, but before its completely
dry.
For the inner rockers, I would spray the insides before they
are welded on with a zinc (aka cold galvanizing) paint. Leave about a 1/2" of
bare metal where you plan to weld, since welding thru the zinc spray will create
a less than satisfactory weld. Also the fumes produced by the burning zinc spray
will leave you coughing for days. Not a good thing.

Subject: [FWDLK] rust prevention - what
to do?
Ok, everyone
agrees that rust prevention was not a priority back in the late 50's and early
60's; and that there is a lot of untreated sheetmetal in our cars. Now let's
talk about solutions.
How exactly
does one treat the inaccessible areas of a vehicle's body, when doing a
ground-up, frame-off restoration? How can one get to all those untreated
nooks and crannies when the body is bare, short of dipping
the entire body in one huge vat of POR-15, a totally impractical
solution?
My 300F
convertible is now fully gutted and the body is undergoing rust repair
and prep for paint. I'd like to ensure that rust doesn't return and, of
course, now would be the time to do whatever can be done. I am just
not sure how to get to all those inaccessible areas. I'd
appreciate any feedback and practical solutions from this
group.
Thanks ,
John
