Dash Paint

When you use auto paint for the dash as in single stage that uses a reducer, the reducer used is per temperature. A reducer for hot weather and fast for cold and all in between. You can uses an even slower reducer to change the way they will cure and shine. Also, many models used a suede finish for the dash but all dashes were somewhat flattened to reduce glare.
I too have used good quality aerosols and have had some gone on stupid dry. Like the co. says, probably due to temp, humidity and even the temp of the metal you are shooting.
There are reasons auto paints cost more!!! And they are up more today too like everything!!!!
