if your keeping it for any period of time or have a concience like me
por15
uses moisture ie water rather than solvents and chemicals to dry airtight
normal paint still breathes hence eventually rusts
and you can paint it on with a brush and it self levels

Hellish expensive and available from the wholesalers in giraween the name of which temporarily escapes me. You could tint it and just spray with it, esp with the self leveling. Uber gloss too.

Only use POR15 if you are going back to bare metal.
If you are not, then there is no point using POR15.

Well you dont have to prime your car if you dont have to , it all depends on the paint thats allready on your car . The 2 pak primer is just something that you would use over plastic filler or coarse scratch marks .What condition is the paint and body in?

lilcrash, are you sanding down to the metal? or just a light rub over the original paint for a quick re-spray?
i use acrylic etch primer on bare metal and acrylic primer filler over that. i like the primer filler as it's easier to get rid of small imperfections in conjunction with a guide coat and once sanded back can be painted straight over with out having to spray a seperate primer.
if i am just rubbing back some old paint that has no imperfections on it, i'll paint straight over the old paint.
you should never leave your car in primer for extended periods of time, as moisture will get through the primer and will premote rust under your primer. meaning you've just wasted your time.
evilldave, are you referring to '2 pak primer' as a primer filler? kinda sounds like it in your description.

ok details
-i have/am rubbing my car back to smooth with a 320 wet paper.(thats wat i was told to use so i cuold primer over it)(im probly wrong again)
-im leaving the old paint as it is pretty good its just faded.
-i dont have much bare metal as wen we did the rust repairs we only sanded the area then filled bak to level with the paint( to make it easyier to paint) or so i thought.
-basically ive just gotta sort out if i have to primer or fill or paint. and wat ive gotta use to do it.
thank you everyone

You could just use either acrylic primer straight over your car if you are going to put acrylic top coat (the colour ) or use 2 pak primer as a filler or as a primer surfacer. If you use acrylic primer and want to put 2 pak colour over the car its not recomended as the acrylic primer is thermo plastic ,meaning it would move underneath the 2pak colour on any hot day. If you are painting your car at home its probably better to use acrylic primer and top coat ,so then you could buff your car to eliminate and dust which my appear in your top coat.Or if you use 2pak primer you can paint acrylic top coat over it , which gives you a hard base to paint over.The 2pak primer also makes it for easyer buffing ,because the acrylic top coat layes down better (it flattens its self out) .The reason why you can use 2pak primer underneath acrylic top coat is that 2pak primer is rock hard when its dry and doesnt move as much as the acrylic laquers do.
