You are living in the past, So was I. The newer base clear systems are definetly the way to go. In the conditions you discribed I would use base clear so I could take my time getting the base as free of imperfections (dust, lint) prior to clearing. All of this with the intentions of sanding and buffing the finish. Centari was a great paint for the day. I sprayed many gallons and still would use it on one of my own vehicles. Good luck with your project,send some pics.
