We are in the last phases of a major remodel and over the course of this job I've developed a friendly relationship with the painting sub. He's a meticulous guy who takes pride in his work. However, he's clearly old style and prefers oil paints and primers and doesn't really know the latest technology. He really didn't want to use Aura for the inside (preferring BM Super Spec) but because our contract specified Aura he did use it.

Now we are doing the exterior and he really doesn't want to use Aura or SW Duration. I think it's because he thinks it's a waste of his money. He wanted to use Kelly-Moore but I think we've compromised on BM MoorLife, MoorGlo, and MoorGard.

Should I insist on the Aura/Duration? Will my paint job not last as long? This is a medium blue-green tone on mostly new stucco. He's very diligent about priming, etc. We are in a mediterranean climate in northern California.

I've read all that I can find about this but I can't find anything conclusive.
