–Called Sprinkler Techs, got $450 estimate for both valves. Called HD Lawn (who did the last one for $185). Guy came out agreed to 2 x $185 for the other two. He’ll do it tomorrow. Sold.
–Sonax polish came in. Supposed to cut well and finish perfect. Tried it on a shaving brush. Finish could be good, but not too impressed with cut.
