Whenever I have rust problems with my truck, tractors or horse trailers, I talk to the folks @ KBS. They'll tell ya just what you need. Their rust products works great. Maybe the KBS System Sampler is all ya need for a small area like that. Just give 'em a call @ 800.304.6740. You can buy your stuff online or ask for someone near ya that sells it.

Remove the rust, you can use a wire wheel on your drill or cut out the rusted area. You then will need to indent the area around where you need to patch by 1/8 to 1/4 inch. Then you can put in some layers of fiberglass or rivit in a piece of sheetmetal. If you use fiberglass, give the final surface a quick sand to help the bondo adhere. Sand to match shape of door.

remove as much of the loose rust as you can by hand then you can buy a sanding disc to fit on your drill it looks like a scrubby pad for the dishes. remove all the rust next you will see a lot of pock marks you can buy a tube of body filler apply in a thin coat sand and repeat. once you achive your smoothness primer sand and paint it .. have fun.

Have you heard of KBS Coatings? You should use their three steo system ... clean, etch, and seal. Once you do that, you can do your body work over it. You really want to stop the rust so it does not spread any more.

Wash and wax car door. Remove all rust with fine wire brush then sand(extremely fine grit). Avoid scratching good paint with brush or sand paper(you can masking tap around bad spot to 'catch' oops. A 1/4 inch of 'good' paint should be lightly tapered sanded(outer most loses wax, closer in paint, closer to rust down to primer(will be different color than paint), closest to rust area bare metal!
Now is there a hole? Hole larger than your finger will require metal patch piece. Otherwise bondo(read the directions) alone will fill nicely.
Sand out smooooooothe. Replace masking tape around area. Tape should be on good waxed part with all sanded to be painted areas visible. Newspaper works well around outside as well with tape= easy clean up too. Now nice and clean and smooth... and completely dry... apply primer... thin coats(two or three with sanding first one or two. Allow proper time for cure before sanding... clean dust before next coat. Now use paint. Sand paint sand paint paint. Thin coats with extremely fine sanding to smoothe rough spots. Final coats should blend into 'good' area.
Then apply quality wax over and into 'good' area. The quality of job will be reflected(ugh the pun) by the coats and sanding!
Common mistakes... too coarse sand paper(highest number best or use steel wool, improper cleaning(still dirty or use of cleaner that leaves residue)too much bondo for area(cracks or falls out), rough spots(inadequate cleaning or sanding), one thick coat INSTEAD of several thin ones, using wrong primer type, using wrong paint type. Rushing without allowing proper cure times for bondo, primer, or paint. Exposing primer to water(NO NO NO) without paint to protect primer.
Good luck and let me know... email me and I'll tell you a secret- those rust spots can happen as water designed to drain from door doesn't and debris/crap/rust clogs up and rust out through door!!! Well still email... depending on overall condition of car/ paint job will determine number of sandings and quality of paint/ primer... good luck!

I would use RustSeal by KBS Coatings. That stuff seals it and you will never have to worry about it again. I bought the 4PAK and it worked very well for me. http://www.kbs-coatings.com/KBS-4PAK-Convenience-Quart-P102C37.aspx
