Here's my situation...

'67S, apart except for front and rear suspension, gauges, and wiring, undercoating is 80-90% off the bottom and fender wells, car was media blasted and primed with a coat of epoxy primer, engine is out engine sheet metal is off.

There is a bit of swiss cheese rust at the bottom corners of the rear windshield that needs to be cut out and replaced, might need to cut out left rear turn signal bracket and replace, other than that there is only one or two areas where there was previous body work.

How should I organize the rest of this project? Should the bottom side be completed before addressing the top side? Should it be painted AND undercoated or just shoot undercoat over the primer? Should the insides of the fenders be painted or again, shoot undercoat over primer? Should the top side be done before the bottom undercoating?

I've partially redone two previous cars, but have never taken one down this far. I'd welcome some coaching from the experts to avoid getting ahead of myself. Haven't made much progress because I don't know which way to turn and afraid I'll make a costly mistake.

Thanks!
