I tried Tamarack and some other stuff early on, but Iben using Magma Blue for everthing for the last 30 years. When I used to live in Commiefornia I called upon GM proving grounds from time to time, and ME is right around the corner. I now live about 15 miles from ME.
Got a Midway heated base for my star and built an electronic setpoint controller that works with a thermistor stuck into the base of the lube reservoir near the base.
