The correct temp reducer/hardner combo is paramount to getting your paint(SS or clear) to lay/flow correctly, or the metallics in your basecoat to lay nice and even as well. Now lets start talking VISCOSITY of said reduced/catalyzed product, thats a whole other ball game :lol:
The trick to laying down SS is to treat it as if you were spraying clear, not too dry or heavy, you have to have the correct mil build, especially if you are spraying metallic SS.
