I'm new to this and I've got some surface rust above the sail panels in my '70 TA. Most of it is in between the two layers of sheet metal where it can't be sanded, so what's the best method for removing it or keeping it from spreading further? Thanks in advance.

Rust, never heard of that before. POR-15 makes a couple things for the prevention and removal of rust. Year one has it as do others I'm sure. I'm going to invest a small fortune in the stuff when it comes time to do metal prep on my 76.

In my humble prof opinion, Although POR products do a fine job for what they are designed for, they are nothing but bandaids. All any of those products do is slow the rusting process down. The only way to truly remove rust is usually more involved than the average person wants or can afford to do.
From the pics you have your in a tough spot to do much with the rust in between the panels. Without seperating the panels and either sandblasting or treating with an acid wash all you can do is slow the process a bit. Ask any reputable resto shop and they will tell you the same thing.
I went the route of acid dipping a floor pan I salvaged from a doner car for my 70 GTO before welding in at all factory seams.
Let me know if you want to talk some more and I'll give you honest advice, not that the POR type products are bad, it's just what you want to accomplish.

rust like you are showing will never be a problem. Rust is natures own protection. Once it forms like you have shown, it will protect the laters underneath. As long as the metal stays dry, worry about other things )

I'm no expert by any means, but how about shooting some WD-40 between the panels? Doesn't seem like that could hurt anything unless you over did it and it start dripping down on everything. Maybe that would keep condensation from attacking the metal further. I knew someone that used to spray motor oil inside the rocker panels on unibody cars and claimed that it kept them from rusting through.

Thanks everyone for your responses. Since it does tend to get a bit moist up here in Washington, I think I'll go the POR route just to keep the rust under control. The car was a daily driver before I bought it, but now it's safe in my cozey little shop and it only comes out to play on warm sunny days.

That's an easy fix. Go to Home Depot or Lowes and buy a quart of Jasco metal prep for about $6.00. You want the green stuff. Pour some of the metal prep into a clean jar and use a paint brush and paint it onto the surface rust. It's real runny and will go down into all the cracks and crevices. It will eat the rust right off and you won't have to retrright over the top if you rinse it with water.

well then, buy this instead opf POR.
