its just 3 spots that are not that bad. the metal belowthe rust is still thick so i don't need to add metal to it. Its very minor at this point.

so sand it down to the bare metal

do i clean it with anything at this point?

then prime it, once, twice? (anything special or just any primer?)

Get the color code which I've gotten. spray the dried primer.

Now the clear coat part. Not to sure about it. Will any clear coat do? I've never worked with clear coating. This is the part that i'm worried about.

I don't want the repair noticable after i'm done. Any tips are appreciated.

as far as painting it, just take it to an auto body place after you do the rust repair and prime it. they can usually blend it pretty well for a decent price. if you want a flawless looking repair, thats the way id go.

youv'e been told what you need to do. to actually repair it you have to cut it out and weld new metal in. that's it.

if you catch it when it's very, very minimal you can sand it down, prime it, paint it, clear it. but this is only a temporary fix in my opinion. the only real way to get rid of it is to actually cut it out.

I can't just fix each spot. I would have to repaint the whole bumper right?
The cars dirty in these picture by the way.

If its surface rust, it can be taken off and prepped. It is rediculous to patch an area of surface rust. There is surface rust on most sheet metal that you will patch with. You are just opening up the possibility of getting rust on the back if you don't get everything completely covered.
