Stymied

I spent virtually all day trying to get two paint spraying systems to work with latex paint. My Fuji HVLP system, which performed so well with the marine varnish on the Yacht Tender, failed miserably with the latex. So I went to Home Depot and bought a Wagner Spray painter, which gave initial promise, but then also shit the bed.

Meanwhile the cubbies could have been completed by brushing.

The weather was great... what a wasted day.

But tomorrow, I'm going to give it one more try by thinning the latex paint. I think that was the problem. If not, I'll be brushing well into Sunday.
