How can I stop frame rust
I'm doing some moderate restoration to my 1969, and I noticed that inside certain frame crossections there is rust on the inside of them. Is there anything I can spray in there to stop the rust or should I not worry about this? The outside off the frame looks good.
thanks,
John

You have to be very careful when spraying products like POR-15 and Rust Bullet. Both of them cure by absorbing moisture and they are almost impossible to remove when cured. Getting some on your skin is bad enough but think of what will happen if you breathe it?
I've thrown out the used motor oil idea a few times when this question comes up. Old New England (and probably elsewhere in the Rust Belt) idea. Spray the inside of the frame a couple or three times a year and the inside of the frame should be well protected from water. I also have a couple areas on my frame that look brand new due to engine leakage. Too bad the engine didn't leak more!

wanna bet that you can easily remove POR15 after it has cured? I painted my floorboards with it and when working on some stuff I stored a can of ethylacetate in the car and sure enough the can leaked and the POR came off very easily after it had soaked in it for a length of time. It's not quite as chemical resistant as you may think.
As for the motor oil, I like ATF, it dries to a nice protective film.

I would try and use some sandpaper and/or steel wool get the rust off and spray rubberized undercoating to prevent the rust from returning.

Being a welder in the salt water marine industry for years. I've found that ozflow say it like it's spelled. I know the spelling isn't right. Just go to any paint dealer and ask for ozflow. When I build trailers and thing like that I always brush this stuff on. Under the vette I used pump spray system. The same system you would use to spray bugs with. 
Home depot has them from $10.00 on up. Make sure to wear goggles and rubber gloves. It well dry in 24 hrs. and leave a white power. Brush off the power and paint if you want or just leave it a lone. The steel is sealed. Remove as much rust as you can. Where you can't get to. use a air hose with good pressure. Then put 2 or 3 coats over that area. This sh#t is the best.
