One of two options:
1. Let it go until it rusts through.
2. Clean the rust spot up and hope that it doesn't go all the way through the pan. If it doesn't, then paint over it to protect the bare metal and check it at each oil change.

Diligence, and rust converter works well.
Sand it down, rust converter it overnight, wipe down in the morning, then prime and paint.

I used that on my boat trailer works great don't need to primer it afterwards either. This is sold anywhere they sell spray paints.

If it's rusting from the inside out, you're gonna have to drop the pan and either get it repaired or get a new one. Either way, you're gonna have to drain the oil and get under there and get the corrosion area cleaned up and determine what is going on.

Yup.. my 2004 had the same issue except it started to leak slowly thru one of the rust blisters.
Was weeping for probably a year before I addressed the issue.Ended up draining all the oil out, used a putty knife to knock off the blisters.
Found a couple of 1/8" holes thru the pan under the blisters.
Cleaned the pan really well with brake cleaner.
Then hit all the rust spots with a wire wheel to eliminate all the rust and get it down to bare metal. Cleaned it all again with brake cleaner. Then mixed up a couple of batch's of JB Weld and applied it to the bare steel on the rusted spots. Did two coats. When fully dry then applied a couple of coats of industrial primer and then top coated with two coats of industrial grade paint.
Worked excellent. No issues or leaks so far.

They rust from the outside in. Starts with stone chips in the paint and then the rust starts to form under the paint on the outside of the pan. The blisters then grow and grow.

rusty oil pan
I noticed this on my 04.5 as well. Was debating on trying to remove the rust and treat it with some type of product and repainting it. Or just replacing the oil pan all together. It looks like the oil pan can be removed with the engine in the truck not sure if it is the best option though, any thoughts?

Wonder if it's salt related? Sandy Eggo ocean air? Other places, Road Salt?
My 06 looks perfectly fine, I'm 40 miles inland from SF and when I'm in Tahoe I'm pretty sure they use sand instead of salt.
Wonder if a Rhino Liner do-it-yourself kit would be beneficial on the bottom of the pan?

Its definitely from road salt. I live in Connecticut and they use a new chemical liquid on the roads and it rusts everything under your vehicle. I,ve had to do brake lines on all the vehicles I own. I have a jeep grand Cherokee and had the same issue. I replaced the pan and 3 years later it's starting to rust again. I didn't paint it before I put it in. Big mistake, the coating does not hold up. As for the ram I got under the truck with a wire wheel and cleaned up the rust best I could and hit it with some rustoleom. It had started to leak as well so I had to put some jb weld on the pin holes that had rusted threw. Been about 4 months and its still good so I hope it holds.
