Any particular brand of bed liner/undercoat?

Should I just go ahead and coat the whole darned chassis or just spot coat it?

Is there anything I should consider when coating for example are there drainage holes I don't want to cover?

i have some similar looking issues beginning to form. I've heard POR-15 is the way to go. Just got me a starter kit to begin with the sway bar before I put the winch on. What I need to look into more is how much prep (read bolt removal, wheel component removal, small parts, etc.) needs to be done before applying it. I'm hoping it is minimal, but I'm guessing it won't be...

The inside of your frame will probably be worse than the visible part so make sure you treat that area as well. Eastwood makes an internal frame coating. I would also remove the center skid plate and clean between it and the frame. Just make sure to support your transmission when you remove it. Looks like you caught it in time. Take your time and treat it right and it should last you a long time. Do nothing and it will break in two pieces at some point!

If you can get your hands on a small angle grinder with a wire knot brush it will take it down to clean metal in a flash.

I just recently cleaned up the rust on my chassis with a wire brush. Then sprayed on rust stabilizer to stop it from growing or coming back. I then sprayed it with gloss black paint. As for inside the chassis I cleaned it out by blowing compressed air into one of the holes in the front and put a shop vac in the large round hold in the rear near the rear tire. After cleaning everything I could get out I sprayed it with Eastwood internal frame coating. I feel much better now that I think I have the rust under control.

East woods makes a lot of different products from fram restore to under coating just got done doing both my Tjs I have used their products in the past with great results. I take my jeeps to the trails in water and the beach where salt water gets in the frames and don't have any problems be sure if you will be in mud and water to drill a 1/4 or 3/8 hole in both side near the rear axle transition this is where I see a lot of other jeeps forming the most rust. Good luck it's not that hard to do yourself.
