I just got my buffing setup installed (1/2 inch threaded rod in a collet chuck with washers and nuts holding the buff in place). A couple questions: (1) What RPM do folks use? (2) Isnit possible to buff when it’s too cold? It’s about 50 out there now and it doesn’t look like the buff is charging at all with the brown Tripoli I’m using. I’m wondering if it’s not generating enough heat.
