In years gone by I did some baked-on gun finishes and made a heat box out of plywood and lined with sheet metal. I used KG Guncoat the 2400 series. Has anything I can do at home been developed that is better than the Guncoat 2400? Easier, faster, better, cheaper, less work or prep? my left over 2400 finishes were so old the had limps in them I couldn't stir out and it is time to reorder.
