I have not used it on my 78 C3 but have on my daughter's 01 Grand Prix which now has 215,000 Miles on the OEM tranny and OEM 3.1 V6. The W body cars are notorious for the rocker panels rusting out in high salt areas of the country and have been treating the rockers for years with other products every year to limit the rust issue. About 2 years ago, I purchased the eastwood Internal Frame Coating, drilled a few holes to internal spray the rusting inside rocker panels with the included flex hose with wide spray nossel and HOLY SMOKES, that stuff is the BOMB!. Stopped the rust dead! I highly recommend it....That stuff is like titanium once it dries. I spilled some on my driveway which is ashphalt and even after a few years of weather, it STILL is in the same place with zero peeling or flaking..STEEL.

I used it on the frame for my 71 before it was powder coated. The stuff works good and the hose extension with nozzle really covers well. The biggest thing to watch is other open holes in the frame. I taped up these holes because the stuff will spray out of them when using it.
I used it on my 1980 frame and I taped a stiff wire to the flexible line so I could guide it up the frame without it snagging areas in the frame and then slowly draw it to myself when spraying.
I have no idea if it will help any because if there is some surface rust inside the frame and you then put paint over top of that, I doubt whether you are doing anything good.

Actually not quite correct. Steel rusts in the presence of water and oxygen, not with either alone. Once the rust starts, water and oxygen are required for the process to continue. If you eliminate either water or oxygen from interacting with the rusting steel, the process will stop. This process is the reason that rust inhibitors work by being able to stick to rust which paint will not and only will flake off over time. When you coat the surfaces you not only prevent further water interaction but you deny the steel oxygen as well...The reason exposed metal lasts so long in the desert even after it starts to rust is for the same reason: Without continued exposure to water the rust process is VERY slow and the reason old cars look remarkably intact in dry environments over several decades......

Ok, ordered a couple of cans in GREEN. Got the pointer about using a solid wire to hold the tube (a welding rod sounds good?), and taping up the holes, and "pulling" towards me as I spray. I guess it can't hurt.
Ordered 2 aerosol cans. I also asked Eastwood if they sold this in Cans of liquid so I could spray with my own equipment. Guess we'll see what they say.
I purchased several cans and plan to do the same. Had to replace both the No. 1 and 4 Body Mount supports on both sides of the frame due to rust. The frame itself was in good shape. Used POR products for the outer frame and did 2 cycles of spraying Marine Clean into the box frame followed by Metal Prep after drying. Will be using the Eastwood spray to coat the internal frame after the OAT warms up - live in the northeast.
Hopefully that will keep from having to do this again in my life time...
I used it on part of my car. Then I realized it would take several cans the stuff isn't cheap. I bought some Rustoleum black rust preventive paint. I put it into a chemical weed sprayer and thinned it out. Bought 2 quarts and thinned them and did the whole frame. I sprayed it in until it ran out of the holes. Then I bought one of those cameras that you can slide up into your frame and got great coverage. These cars will never see real water anymore so I guess it will last another 50 years.
Thanks for that. I guess I'll use my 2 expensive aerosol cans and if I need more then I'll get some Rustoleum rust preventative paint. I wrote to Eastwood and asked them if I could buy this in cans so I could spray with my own equipment and they responded that it was only available in those aerosol cans.

it took me almost one can to do the rear end crossmember.
I had my 77 frame acid dipped and epoxy primed. I used eastwood internal coating for every channel and rail. I taped up every hole I could fine but in the end stuff still ran out. I just cleaned it up after it dried and then applied a second coat of epoxy primer to the frame. That was 6 years ago and no rust I can find.

My guess is we will all be gone before your frame EVER rust out................with that type of rust prevention............
I used to spray parts for friend of mine who made parts for the Dept of Defense for military vehicles.
I was at the shop one day when the federal inspector was inspecting what I shot the night before. He was checking on mil thickness and other stuff. One of the tools he had was a tool that when it was attached to the part. IF a spark from the wand that he put up near it would create spark it would fail. Because like he told me that they do not want ANY pathway for the coating to beign to fail.
He then told me that automotive paint is some of the crappiest paint out there in regards to this specific test. He took his tool and hooked it up to my car and when he ran the wand near my paint...it was sparking like cray. AND he said that each spark was a path to where the metal was exposed on a microscopic level. I was shocked and amazed.
So...knowing that the special primers and paints I was using when I shot this stuff. I know that there are products that can seal off metal so not air/water can get to it.
Here is some feedback for eastwood internal frame coating. I used it on the inside of my powder coated frame aswell. With some left over cans I did my birdcage and windshield section that I knew would be left under driveway under a car cover for some time( think its been there for 1-2 years now). It was pretty badly rusted and I did not want to do the repairs until it was actually the time but I did want to stop the rust for the parts that could be saved. I cleaned it with wire brushes also wet sandblasted some areas and used a rust inhibitor that I've had good results with called krudkutter rust inhibitor. Then after a few days I sprayed with the eastwood internal frame coating when fall season came I put a car cover over it and it stayed under covered driveway since then here's some rust starting to show after I think it has been 2 years now.
Here is the body mount areas some sand has gotten back in there. It may be a reaction from the frame coating not pentrating through the rust inhibitor in the heavy areas, I can't remember if I hit it with a wire brush after the inhibitor or washed it off I think I did can't remember. I may grind down the areas where the rust is showing and spray some the eastwood again and see what happens.
Ive had good luck with this acid based stuff in rusty areas on my truck... the stuff burns when you get it on your skin so nitrile gloves are a plus I did topcoat this in areas with the rustoleum black rust inhibitor primer and overall with a "Rust kote" spray on veggie oil based undercoating but no actual paint. Time will tell as this is the first winter with it.
I hit it with the drill and wire brush to see whats underneath and the metal still looks clean, I guess the car cover itself was wet or so causing surface rust or something that had rust on it rubbed off on to the paint
Eastwood internal frame coating?
