Any Ideas on Frame Preservation?
Greetings to all. This is my first post.
I have a 78 Vette with a good solid frame and I want to keep it that way. I bought it in '88 and have had it stored since '91, 67K actual miles. I am in process of replacing the exhaust with true stainless duals and want to do what I can to preserve the frame before putting on the new exhaust system. There is a little surface rust on the frame but no holes or rust through. I don't really want to take the body off the frame at this time. I am preparing the car to use as a driver and to take some trips out west. Any ideas or suggestions for preserving the frame? Por 15? Spraying inside the frame with rust reformer followed by paint? What has worked well for you?
Thanks for your time and suggestions.

I am about to do it to, and from the information i have gathered on this forum POR 15 seems to be the best thing to do if you dont want to do a frame off and powder coat your frame!
I will be using POR15 on mine soon...
If you do a search on POR 15 or on frame paint you will find a lot of info.

POR15 works great on the outside.
Eastwood has a new product for the inside of the frame.

how about wd-40, PB blaster or any other light oil of choice?
The concern with hard or thick coatings is that when (not if) rust gets behind it the rust accelerates.
i have some powercoated rally wheels that prove that. Moisture gets trapped behind the paint/coating and it stays wet all the time.

Thanks for all replies so far.
I am planning to paint the outside of the frame with black POR 15. There are some areas that I will obviously not be able to reach with the brush.
For the inside of the frame I plan on blowing the dust out with compressed air and then following by spraying with Ospho. Ospho is a rust reformer/converter product that contains phosphoric acid and converts the iron oxide to iron phosphate and stops the rust. I will apply this using a siphon feed undercoating wand that is 36 inches long and 1/2inch in diameter; I obtained this wand in an undercoating kit for a product called "Rustfree". After a couple of days drying time, I might follow this with a light coat of black enamel thinned with a bit of turpentine to improve flow out and slow drying time; this applied with the undercoating wand the same way as the Ospho.
Any comments or suggestions? Thanks for all replies.

I like to take a good pressure cleaner to the inside of the frame, amazing how much stuff can be in there. Then the phosphoric acid with multiple applications before it drys. After that it's really your choice, There are some paints that will work well or you can use some of the waxy preventatives, lots out there. The military even has specs for them and are manufactured by most of the big oil companies, like Chevron, Texaco etc. Sort of pricey, but they work.
A syphon fed wand is hard to get to most inner spots, but I've had success with a flexible hose on the gun instead of the wand, doesn't have to be fancy, increase the air pressure and it will splatter all over the inside of the frame. Cover the floor, lots of runoff.
Best would be hot galvanizing, but that's un undertaking.
