If you sand to bare metal, it will flash rust rather quickly, unless you put a protective coating (i.e. epoxy primer) on.

Assuming the surface rust in minor like you say, I guess it wouldn't save you a whole lot of money by presanding the areas. Take a couple of pictures and show them to your painter. Discuss your options with him.

 

Those spots will definitly need to be taken down to bare metal, you could probably save a lot of money, by doing that yourself, and then cover the spot with a good primer till your painter finish sands it..

 

Thanks for the help....... can i use a spray can primer like dupli coler filler primer ???? thanks Bruce

Haven't use that brand of paint so I can't comment on it directly. Just remember the primary rattle can primer rule, "Primer is not waterproof". An additional thing to remember is that your paint job will only be as secure as your weakest link. If your primer is of poor quality, then your paint job will be of poor quality.

Again, this is just general primer information. It is not a reflection of what I think about dupli coler filler primer.

 

That primer should be OK for awhile, epoxy type would be best, but I'm not real sure if you can get it in a rattle can, anyway when the painter finish sands it, he may take those particular spots back down anyway so you should be alright..

 

Sand the rust down and sandblast out the pits in the metal, if there are any. If you don't the rust will return in no time and all your work is for nothing. As for primer in spray cans, ask your paint what manufacturer he uses for paint and if its compatible w/ the spray can primer. As for the type of primer you want to make sure on the bare metal areas you use epoxy or etching primer first.
