Mark: 

It was 17 days start to finish with 3 days out of the yard resting from sanding. We had 10-20K winds blowing through the yard and a couple of 100+ days -- not that much fun weather wise. 

The gray white gray is to make application easier - ie reduce holidays when painting grey on grey on grey.

The red then blue - should make the rough sanding easier at the next haul out - ie stop sanding when you hit the red paint!
