I’d just finished painting all the walls, two coats with a quality paint. The next step: to apply white enamel to the baseboards to set off the new tan walls, so I grabbed the handy and thoroughly cleaned 3” Purdy brush I’d used on the kitchen enamel. That’s the one on the right in the pic. It worked well for the first 20’, but began to hold more paint than I could scrape off, and it began to drip onto the new tile floors. Not a good thing. And, once again, that reaffirmed what’s close to an absolute truth...
