I am beginning to see rust bubbling under the pain in a few spots on my 69 - a few on the lower parts of the doors, and on rear fenderwell lip. The paint job the previous owner did sucks, and they obviously didn't do good/any prep work.

My question is how can I repair these spots as they come up without looking like those cars that you see with primer all over?

Just use a dremmel and use touch up paint???

The real question you first want to ask yourself is do you want to hide the rust for a temporary period of time or do you really want to fix the problem. if you see bubbles now, multiply the size of the bubble by about 20 or more and you'll have a better idea of just how much rust lurks beneath your paint. Be prepared, if you choose to really cure the problem, to go deeper than you expected to get it done right.

Well said.

For now I'd say the touch up is the way to go. The areas you're talking about are about impossible to stop from rusting on a daily driver unless you really start cutting and replacing. I've had good luck squirting heavy oil (Harley oil works good) in the inside of the doors and around the rear inside wheel wells, but it gets messy seeping out on the floor for a couple days. Will slow it down though.

MURFY_S LAW - I completely understand what you are talking about. I have two quarters that need replacing yet when I bought the car (when I was young and dumb) they looked fine. When I got around to sanding them down I found that the rear of the quarter panels from the bodyline down were built up with over 1/4" Bondo. I also found a home made patch panel rivited into place and a sock (yes a sock) between the trunk dropoffs and lower quarter panel (obviously used as backing for the artistic Bondo job).
