Ok So my oil pan of the 4AGE was taken off and since it had a lot of rust inside and outside from sitting in the rain. I decided to strip off the paint inside the pan and outside using a sand blaster to knock out rust and ect.

So now I have a shiny metal pan, but Im not sure what to really coat it with since its going to be going through oil and what not's in a motor.

My Question is what do you guys use to coat it with. I know you must use an Anti-Corrosive spary but im not really sure which one since non of the auto parts store know of this. They only know of new parts.
If you guys can help out that be great. Cause I'm stuck and please no mentioniong of using color paint to coat the inside case thats not going to help with cooling and oil.

i'd suggest a good enamel for the outside of the pan and nothing on the inside. its going to be in contact with motor oil all the time, it shouldnt need any paint. if you do want to paint it, again a good enamel paint. just be sure your surface prep is impeccable. no grease what-so-ever, not even oil from your fingers and skin. might want to reblast it with something sharp to open the metal to hold the paint better or scuff it with some 220 grit paper, then degrease again with brake cleaner or a good prep spray.

DON'T paint the inside at all, It will most likely not stick with the oil etc, and could come off and plug your oil pump and/or oil passages.

Outside, use any engine enamel from the parts store, even after sandblasting, I usually will heat it lightly with a propane torch just before painting to boil out any excess oil, just takes a couple minutes and makes the paint stick better, you can see the oil film evaporate off as you move the torch slowly along, then let it cool down to just lukewarm and prime it, then paint.

every oil pan ive dropped or installed has been painted on the inside, so there is some kind of paint when correctly applied does not come off.

Yeah thats what I have noticed, plus its not stainless steel so it will still rust eventually.

eh, i dont think the inside will rust really.
