I just finished helping a friend paint the interior of probably our 20th
house in the last 10 years. Typically he rolls on the latex to paint the
walls and I cut in. Also I do most of the oil based enamel trim painting.
Through the years he has always used thinner to thin the paint and to clean
the brushes. It has always been a pet peeve of mine to come back after
lunch and begin the trim work again. I always clean the brush in thinner
before leaving and when I resume painting the residual thinner in the brush
blends with the paint in the brush and runs down the handle for the next
hour. I HATE THAT! And It never starts immediately, it begins 15 minutes
after thinking I am starting with a "basically dry" brush. I often will
prime the brush with a very small bit of thinner but what resides after
cleaning is way way more than "a bit".

This time around he brought mineral spirits, odorless AAMOF.

I noticed,

1. No odor, although Swingman would testify that is smells like a refinery
13.6 miles NE of Pasadena, TX had just released .003 atoms of smelly stuff
into the atmosphere about 15 minutes prior. ;~)

2. It works just as well as thinner for cleaning the brushes.

3. I never once had a friggin dripping brush after lunch.

Does mineral spirits evaporate faster than thinner?
