I need advise on bumper, lower exterior trim paint.

Which brand paint and primer and how much of each to do the following?

Over the past months I have become proficient with an HPLV spray paint gun. I used a detail gun to shoot all the vinyl and leather inside my 85 MB w126 short body car and even used one to spray Interlux Perfect Plus, two part clear on the zebrano trim.

I'm pulling the bumpers, lower trim, exterior rear view mirrors and inner grille grid and reworking/restoring what I can so I need a paint which will last. I also have no idea which primer to use, how much to buy without half a gallon of waste or how much finish paint to buy.

If there's a professional or experienced person here to point me in the right direction I be much obliged for advise.

For the record, a quart of 2 part basecoat and a quart of 2 part clear is more than enough. A pint won't do all the exterior plastic on a w126.

I used a HPLV trim gun with a 4 oz cup. The paint/clear gives the pot life at a certain temp. For every 15 degrees above that temp the pot life will be cut in half.

exa: Pot life 2 hrs at 70 degrees F. Pot life will be 1 hr at 85 degrees F.

That will suggest how much you mix each time you mix. You guys probably knew this. I didn't.
