Hi Eric, I think Centari is an very good acrylic enamel. I have used it quite a number of times in the past, most recently when painting one of my trucks last year. It is currently mixable in three different ways, depending on which additives you use; 1) Centari Ultra - an "acrylic urethane" modification with performance pak and special reducers, 2) Centari - another "acrylic urethane" modification with hardener and conventional reducers and 3) Centari - a straight acrylic enamel with conventional reducers. Both urethane modifications contain isocyanates in the performace pak or in the hardener. The straight enamel is iso-free. Make sure you get the appropriate product data sheet from DuPont before using though. If you choose the Ultra variation, arguably the best of the three, the technique is quite different than usual for enamels...e.g. you go immediately to the second coat in a cross-coat technique with no flash time between coats. I found this variation quite easy to spray without runs. The performance pak "hardener" is a more sticky type of additive than I am used to for hardeners. You may not be able to get Centari mixed in exact replacement tractor colors any more. I think the non-automotive colors have now been relegated to an economy line of DuPont paint products called Nason. My comments above are not applicable to that line of products. I don't know how much longer DuPont will continue to produce the Centari line...or at least how much longer local suppliers will continue to mix it. Single stage enamels are slowly being replaced with base-coat/clear-coat urethanes in the automotive refinishing trades. PPG has just about discontinued their great Delstar acrylic enamel (a competitor to Centari)...at least I can no longer get it mixed locally at all. The same thing may happen to Centari in the near future. Rod
