Hey guys. Sorry to start a new thread about this but I haven't found the question I've got. I applied Meguiars polish to my car using my new PC orbital and was wondering if I need to mist the polishing pad at all. I saw one video that was referenced here and the guy did that. It also says on the directions to not let the polishing compound dry. It started to dry rather quickly and I don't want to use too much. Any thoughts? I'm using the white pad that came with the buffer.
