por 15 inside of my frame help

The other day I was giving my jeep some much needed attention and found chunks of rust inside the frame. Without doing a full frame off, what can I do to prevent this from rusting further? Is there a good way to por 15 the inside of a frame without removing everything?

Thanks,
Spencer

P.S. i found lots of threads explaining how to por 15 the outside of a frame but nothing on the inside.....

Back 15 years ago I remember seeing a long tube that connects to a spray can. The end of the tube has a nozzle that fans the paint out to the sides, not the front like a normal nozzle. How it works is this. You stick the tube all the way in your frame rails. Then as you are spraying the paint you slowly pull the tube out. That way the rails get an even coating of paint on the inside.

It's the same concept they use for undercoating the inside of your frame. It works well.

Eastwood has a frame sealer thats made for the inside of frames. I forgot what its called but it comes in a spray paint can and a 24" wand to really get it all in there. Im hoping to do it to mine before winter

That's exactly what I was remembering. I thought it was from Eastwood.

Internal Frame Coating w/Spray Nozzle

I did this to my '01 earlier this summer. Works great. I only used one can, if I had it to do over, I probably would have bought a second can. You need to tape over all of the holes in the frame or the coating will spray and drip out. I also found it on Eastwoods Ebay site for about five dollars cheaper than the actual Eastwood site.

I used POR-15 on some rusted farm equipment. I found that without proper prep work as per the instructions, the POR-15 would not bond properly and chips off easily.

With proper prep work the stuff works great...as advertised!

If your going to spray POR-15...make sure you wear proper respirator, nasty stuff!

I need to attack my frame inside & out. I noticed it has scaling rust and dirt inside the frame where you can stick your fingers in those round holes - I'm taking a hose to that and may use this Internal Frame Coating spray and/or Fluid Film to keep the rust at bay.

When you have rust in the frame, there is just no way to get it out.

POR 15 is great stuff, but have you ever considered just dumping some 85-140 gear oil down the inside of the rails? I know its not as nice as painting it but just an idea.

Oil would most certainly work it just will work it's way out over time and trap dirt. Could get messy.

Old timers would rub old oil on the frame. Yes, it traps dirt, but wipe that oily dirt away and you'd find nice shiney metal underneath. It works if you reapply every say 3000 miles or 3 months. I think the problem with the inside of the frame would be how to get the old gunk back out. Degreaser? I just heard about the Eastwood stuff a couple of weeks ago and while I don't have any rust issues, I'm going to treat before next winter anyway. I heard four cans is the way to go.

Internal Frame Coating w/Spray Nozzle

This is the link to the internal frame coating product by Eastwood. I have done my rusty 97 and it really cleans and seals things up nicely. One of the posters above said it was impossible to get the rust out of your frame and that is not true. Takes a bit of patience and work, but it is important like with all paints and coatings to have a clean and dry surface to start with. I used a telescoping magnet on a long flexible pole to remove all loose rust inside my frame before I sealed it. It is tedious, but I pulled pounds of rust scale out. I started on the ends with compressed air and blew debris to the middle. I held a shop vac in place over a frame hole and this caught a lot of scale as I was blowing with the air. Then I just worked the magnet. I was able to get both frame rails clean and then I used the Eastwood product. I used 2 cans per side. Be sure to tape over the holes in each section you are not inserting the spray nozzle into. Also have some rags handy and put some paper on the floor under your frame rail to catch drips. I applied it liberally. 2 days later I had a hard finish inside my frame.

If you off road a lot it is easy to get sand and mud inside of the frame. It is important to wash that much out frequently and it attracts water and encourages rust. Once you have your frame clean and sealed, keep it clean!

Thanks for all the replies. So a magnent and my blow gun and several hours. Is its smart to di 2 coats letting it dry completely between each. I just bought 2 cans is that enough?

You need two cans per side to coat it properly. I put one thick coat on since a second coat would not be touching bare metal so I didn't think it would do any good.
