I don't have a needle gun, but I have this nifty set of air tools my wife bought some years back. I have never used the chisel! The chisel has an assortment of tips, one being a single point, used like a scaler. This, and the flat edge, work well inside the body mount brackets and the joints where metals meet.

After looking at the frame this morning, everything that was cleaned down to bare metal has a layer of fine surface rust. I ordered a POR-15 kit off Ebay this morning. The kit includes the Marine Clean, Metal ready, and a quart of POR-15. It should be more than enough to do a frame. I'll use black implement paint for a topcoat.

I must not be living right! While grinding away I found 3 different cracks, small and easy to fix, but cracks still. The most significant problem that I found is frame rot at the back of the frame, under the front spring mount. The rot is right in the frame weld. Guess I'll have to remove the spring mount. What are my options? Do I grind the rivets down, fix the rot and weld the mount back on?? Can't believe I almost put this thing back together...

I read/skimmed all of the previous post, a lot of good advice but ill just go ahead and give you my 2 cents on some of the topics.

Herculiner is a decent product, but surely not the greatest. I can understand the use of it if you dont have a bunch of money to spend. But if you do, go big. And by that, I mean go Line-x. I can get you the chemical breakdown and differences if you would like. Let me know.

Assuming you are going with herculiner. Get the surface down to the bare metal, like you did with sandblasting. Then you want to remove all of the dust, however you want. Then you need to clean the surface. This also scuffs the surface a little bit. I suggest denatured alcohol, I use it everyday.

To make your life easy. Take all the bolts and screws that you can and put them in the frames holes in which they belong. Be sure to apply white lithium grease to the head and threads before hand. This way when you are done spraying you can pull them out and have perfect threads. Not to mention the liner will come right off your bolts. Then soak the bolts in alcohol to remove grease.

That light rust you mentioned is not a big deal but if you can avoid it then do. Otherwise, you won't see it affect that frame in your or your sons lifetime.

Let me know if you have any other questions

Thanks QuickCJ- I'm not going back with a bedliner material for a frame coating this time. I am going to coat it with the POR-15. I plan to use some low gloss black implement paint (I have some already) for a topcoat.

Where could I find denatured alcohol without ordering? I live in a very small community. Nearest "big" city is an hour away. Am I cleaning the surface with the alcohol? How does it scuff... chemical reaction? Or should I be cleaning with a wire wheel and alcohol? I don't want to blow anything up!

Thanks for your input.

You should be able to find it at any local hardware store. You just need to spray it on the vehicle and wipe away. It will evaporate almost immediately, so do sections at a time. Do this right before you treat, paint, bedliner, whatever it may be. You'll be happy with the results.

I should finish grinding the frame today. Hopefully, my buddy will be able to fire up his welder this weekend, and we can get the bad places patched. I have everything I need to git 'er done, but I am limited by my own lack of skills... that's killing me! My POR-15 kit arrived, ordered from Ebay. The purchase was right-on. The Vendor was prompt. I recommend the POR-15 Outlet.

Just want to give you an FYI I do recall some people having problems getting regular paint to adhere to the POR-15. Its a good product and I am using it too. But I have not experienced it myself just in what I have read...
Good Luck

85 CJ7 Build in progress, 258 with T-5 and dana 300.
Fiberglass tub Raptor lined interior, rustoleum lined the underside. Modified family roll bar from fender mounted rollbar. Full tie ins to the frame soon to come.

I appreciate the heads-up. I will seek good info before I paint.

I plan to use the Raptor on the tub... didn't think about it for the frame.

More bad news for me... another crack found. Da**! It's getting depressing. My buddy had a Larynectomy awhile back, and had a procedure done today. He will probably not be in a welding mood for a week or so. Should I be concerned about the surface rust that has formed on the bare metal? If so, how should I prevent it until coating the frame.

Picked up a gallon of denatured alcohol today from Lowe's... $16.

Surface rust is fine. Don't sweat it.

Thanks Pac.

I have also found that nothing works as well at removing the old bedliner as the air chisel. It pops the bedliner and primer coat right off, with no effort from me. I don't know if it is because of poor adhesion, or what. I run it at 40-45 PSI to keep the tip out of the metal. Wear ear plugs and eye protection.

Sorry, haven't read the whole post, but I used Rustoleum bedliner and Rusty Metal primer to finish my '53 CJ3-B's frame and it looks fine. HTH
