Like some guys said I heard foam spray and that kind of stuff just holds water in and makes it rust more. I plan on using this stuff this summer when i clean my frame up.

The best way to coat the inside of your frame is take the frame to a galvinzer and have it acid dipped then galvenized. A friend of mine did this to his f350 frame a few years ago and it worked great. Other than that clean it out a with a powerwasher or garden hose when you wash your jeep.

The Brits have a product called Waxoyl that puts down a nice waxy film. It is used on inner panels like frames and inner rockers.

You can make your own by mixing lanolin with paint thinner.

If you want to go all out, check out Aircraft Spruce. They sell special aerosol products that are engineered to wick uphill inside all areas of an enclosed cavity and deposit a rust-inhibiting coating that flexes and deals with rust or grease already in there. They are used on older aircraft where corrosion inside a steel frame is a very expensive and dangerous condition. The aerosols are a little pricey but well worth it in terms of ease of application and piece of mind.

im going to try to bring this thread back to life, maybe get some new ideas. today I put a garden hose in the larger holes on the side and blasted it with water, then I took a shop vac and duct taped a clear plastic flexible hose onto the shop vac hose and snaked it through the frame and sucked up all the water, dirt and chunks of rust that didn't drain out, next im going to spray the inside with the eastwood internal frame coating.

That's exactly what i plan to do to my YJ when I start working on it. I already have the Eastwood internal frame coating cans in the barn. Just have to finish with my big sidewalk and retaining wall project before I get to work on the Jeep.

I hit all of the frame holes whenever I hit the car wash. When I got my Jeep, the rails were packed. I might have some rocks in there, but no more mud comes out.

What if there are rust flakes in the frame larger than the hole near the rear LCA mount?

I'm still confused on the best way to blow all this crap out of my frame rails before I coat them :\

A coat hanger or screwdriver can maybe break them up, but if your frame is that rotted inside and shows any cracks or rust outside, it is time to look for a replacement. Someone cut holes in the tail end of my replacement frame so they could get all the crap out, then they blasted and painted it up pretty and sold it to a sucker, me... I even coated the insides good with cold galvanising compound before installing, but it was too late. Just street and dirt road driving caused it to fall apart, it was just plain rotted from the insides out.

Make sure you tape all the holes except the one you snake it into...It gets EVERYWHERE!

I did this cut (to patch rust) after I coated the inside.

I had the luxury of having the frame completely bare - I just beat it with a mallet, cut some holes for the stuff to fall out, and shook it around and let all the stuff fall out, then stuffed a hose in there and cleaned it as best I could. I guess if it was still a jeep you could blow/vacuum the rust out with compressed air/ pressure washer/ vacuum/etc.
