Ok, so I have searched a lot of places but haven't seen much on treating rust in places that are not really accessible. That is, inside the roof under the ribs, inside the cavity above the windshield, inside sail panel areas, etc, etc.. It seems to me that blasting doesn't get into those areas well enough.. There is a place in Portland, Oregon that does full submersion stripping but I don't know if the VIN tag will survive... If you do dip, can you really get a good paint coat back in there.. As a good survivor, my car has mostly surface rust in those areas and no rust through... My car is on a rotisserie so I can roll full 360 degrees without difficulty.. For those that have been doing complete restorations, what have you done and how well has it worked....


Thanks.....

 

Dipping has one serious drawback and that is you have to work really hard to get the fluids off after. The fluids accumulate in every nook and cranny. What you discover too late is when your painting the pressure of the spray will cause a little fluid to run out on occasion basically ruining the paint job. Dipping is done but use care and be aware of the draw backs... In places on these car the dipping process can result in the body looking like Swiss cheese and leaving more repairs to do than most people are prepared for... Media blasting seems to be the best alternative but again you can wind up with working for days to get all the media out...

 

I've had the same issue in trying to get paint, or sealer into places you mentioned. If I'm replacing rockers, or panels, I spray them prior to welding them in. It means the welding will still leave some places that will burn paint off, but it's better than nothing, which is what the factory did.
I've also found that I can often put a lubricant nozzle/tube on rattle can paint, and it allows me to shoot a very heavy, wet coat of paint into almost inaccessible places. Whatever I can do to make it better, I try to do. But considering most of our cars wont see the heavy rains, and daily use they did when new, anything we do will make them last longer than most of us will be around to see.

 

Garden sprayer and Ospho?

 

Rust encapsulater spray, works well at stopping rust in places you can't get at.
Leaves a black paintable surface.
