I am restoring two old pickups and am going to be ready to paint soon. I have been looking at the turbine type systems because they warm the air and have no potential to mix oil with the paint. Eastwood used to sell these systems but no longer does, why? Can you give a comparison of the systems and the advantages of each? Also can I get by with a non-fresh air respirator if I take a break every 20 – 30 minutes? thanks for the great products and the knowledgeable assistance. bob
