surface rust prep before paint question again

I stripped my car again a week ago, after trying to paint it myself, and took it on a trip to get a bid on a paint job. 4 hr. trip. I ran into a very light rain and with it covered had some moisture get under the tarp. Now I have some very light surface rust. Really bummed me as we have had 20% humidity here for a month. I tried sanding it and it came right off but I am worried if sanding is all I need on the car or something else. I did a search and got confused as to if it fit my exact problem. It goes for paint next Thursday.
Thx! Walt

Didn't say what you have on it now? Is it bare metal? Some years ago I stripped my car and primed it with lacquer primer (I know better than that now) then after a couple of days I wet sanded it then let it sit for the weekend before I started back on it for the final paint. There was a few rust spots showing and when I started to sand these out I found that the entire body had rusted under the primer so I had to strip it again. My point is that if you have it only in primer and there is some rust showing after a brief exposure to moisture it is a good bet that the rust you see is only a small part of what is actually there.

If the car is bare metal right now, I would suggest that the whole car atleast be sanded thoroughly before primer. Then it should get a good epoxy primer job before going any further. If you prime over what you have, you will most likely have rust very soon. It should have been primed with epoxy as soon as it was stripped.

Using Dupont's Metal-Etch or POR's Metal Ready on the bare steel, prior to priming, will give you some time before the panel starts to re-rust. If I know a panel will be bare for a while I simply wipe it down with either of these and I know it will be clean for a long time. Both products contain Phosphorus which leaves a coating on the surface which inhibits rust. I have used these products for years with good results. These products will also REMOVE minor surface rust if used with a Scotch-Brite pad.
If I was in your situation I would wipe down the entire car really well to remove most of the rust then, when you get ready to prime, hit each panel with your D/A and some 320 grit on a 3M softpad. Wipe it down with a good pre-cleaner and you'll be good to go.
