<VV> rustproofing a '64 convertible

I have a very rust-free Arizona '64 convertible that  am about to start 
restoring. I had a lot of water coming into the car via the heater 
outlets on the inside of the rockers. My understanding is that water is 
meant to pour into the rockers from the openings in front of the screen 
(the previous owner had tried, rather optimistically, to blank these 
off). It is then meant to pour out again through openings provided. 
Obviously if these outlets become blocked, the rockers will retain some 
water, or in my case, a lot of water! If you live in an area where there 
is salt on the roads, that is a recipe for disaster. You're never going 
to stop it getting in there in the first place - you just need to make 
sure it can get out again.
What I would do is pour a cavity wax sealer into the rockers, while 
making sure all outlets remain clear. I like Eastwoods internal 
protective wax, whatever they call it. Green stuff you spray in through 
a thin hose with a 360 degree nozzle on the end, although I might be 
inclined to pour it in until it pours out everywhere. It should find its 
way into the welded seams and stop any further damage in those areas.
I should add that I do not claim to be an expert on Corvair body 
construction, so those more knowledgeable may differ.
