Red Copper Oxide Paint?

Personally,I would think about using an aluminium oxide primer, which is compatable to both aluminium and mild steel.

Make sure that all surfaces are spotless before you start!

Pos - what you need to do is physically seperate the two metals. Paint will work to an extent, but it fails eventually.

What you want to do is get a can of seam sealer (halfords, good auto paint shops) it costs about £10 and you will end up using it for loads of stuff when you have it, so well worth having.

Gently pick the door skin back, cut out the bad bits and clean up the skin and prepare your new metal.

Prime the skin and let it dry for a day.

Apply a thin coating of seam sealer with a 1" brush (cut the bristles down to make them more stiff). Lay it down and get it the way you want it quickly because it starts to set within about 30 seconds and if you rework it, it will ball up.

Once it's dry check it for cracks, if need be apply another thin coat.

Paint the back of your replacement steel with several coats of a good primer and then a good top coat, this is well worth spending £15 on to get some decent paint and doing it properly.

Line it all up and weld in place, use very quick short bursts with long cooling periods inbetween on the base plate of the frame to avoid burning the paint.

I would then run seam sealer between the frame and the skin to stop water getting in and causing the corrosion in the first place.

You can also fix the door handle area to stop water getting in and running down inside the door.
