I have a fair amount of surface rust on roof, doors and hatch and figured i should probably take care of it before it gets any worse. I am not planning on having the car painted for several months so what is the best primer or surface protectant to use after i get the rust sanded off.

Boy that's a tough one! There must be hundreds of different products that you could probably use for rust conversion. Several that stand out in my mind (IMO) would probably be "Picklex 20" at www.ashjentech.com (NOT CHEAP...So stand by for some sticker shock) I've got a batch heading my way as we speak. Another good one would probably be "Metal Ready" at www.por15.com (Also have a very good selection of "Heavy Duty" paints) Another possible choice would be "OxiSolv" at www.eastwood.com.

As far as primer goes I'd recommend DP90LF epoxy primer (PPG Product) They also have other primer colors as well. (DP40LF (Gray-Green), DP48LF (White), DP50LF (Gray), DP60LF (Blue), DP74LF (Red Oxide) Any local paint jobber shop should be able to help you out procuring that item, as well as thinner, tack rags....etc...etc. I also found a url on the web that has what they call p-sheets on each PPG product that you might use. url as follows: www.tricitypaint.com (Each p-sheet tells you "Exactly" how to mix it, apply it, what not to do...etc...etc. Hope this points you in the right direction...

I sanded off any and all rust found and am using epoxy primer OMNI MP 170 , it's a self etching primer. $50.00 a gal. and I will follow it up with a med. fill primer . I am not shooting over any rust just clean sheetmatal and what is left of the origional primer and paint that was good. my 2cts
