John, most all the synthetic enamel type [Synthol] paint hardeners will work in the synthetic Deere paints [I don't know about the fast dry Deere paints though].. ~ If you are going to use JD paint I like the NAPA part #8010 hardener, this is Synthol type hardener. Read the can for mixing directions but most are 1 part hardener to 8 parts unreduced paint. I would also recommend using the NAPA Synthol reducer as opposed to JD reducer as the paint seems to lay down better... NAPA does have different temperature range reducers available…. 8005- (55-80 degrees)--[fast drying]
8004- (70-90 degrees)-- [medium drying]--- Probably close to what Deere's reducer is…
~On the mixing ratios: That is kind of determined by your painting equipment, painting technique, air pressure, painting conditions, air temperature.. The hardener usually remains at 1oz hardener to 8oz paint but the reducer ratio can vary a little. I usually use a mixing ratio of 8 paint, 1 hardener, 2-3 of reducer but have dropped back top as low as 1 of reducer if the Deere paint is thin like on the Deere yellows.. My best suggestion on the reducer ratio is to start at 8 paint, 1 hardener, & 2 reducer, then paint a test piece & see how the paint lays down & glosses out [once you see how it paints out you can adjust the reducer ratio].. Don’t try to paint it out flat to begin with, some orange peel is normal with enamel paint when spraying & it should lay down flat while flashing off..
~OK now on that hardener… Be real careful with the stuff, [paint hardener contains Isocyanates] .. Isocyanates are very bad for your health & should always be kept off the skin & out of the lungs.. Personally I use a pressurized fresh air pump & full face mask & keep my skin covered while painting with anything containing Isocyanates.. See heath & safety risks before using any paint hardeners.. Even most canister type masks don’t do a decent job of filtering out Isocyanates in the breathing air.. JDClooney@aol.com
