Primer Question, Prime now, drive, paint later. Options

[ruby914]

OK, I have my flares on.
I am fumbling through the clean up body work that goes with that and finding other body work that is needed as I go.
Cass Nawrocki's book has already helped.

The thing is, this car is one of my (2) 914 DDs
In order for me to get clean lines on the body I need to remove the last 3, 4, 5 or 6 paint jobs.

I have some 5 Star 5425 X Treme 2K Direct to metal Primer Filler/ Sealer.
After I go down to the metal and spray with the sealer mix ratio, can I trust this to drive the car? Even park out side in the moist air, in the rain???
Then paint later, 6 months, 1 year later ??
What can I get away with?

Every coat of previous paint you leave on is another persons work you're relying on to be done correctly. . . do you really want to do that ?? Also, I'd want to know whats underneath all that old paint. . You don't want to be doing this all over in a few years. I'd sand it until you hit the original primer everywhere. . . There has got to be a bunch of old door dings and filler on the sides at best. . .

By the way, PPG DP40 is in a bunch of colors, It's the best I have found for a metal etching primer that can be thinned to be a sealer also. Not cheap, but worth the expense. And do it all the apinting at the same time. PPG's instructions say it must be painted within 1 week Anything more than that, they say it must be sanded and recoated before paint. Don't leave the primer exposed to the outside. Contaminants are your enemy, and they are in the air all the time.
