Not matter what paint you use this will bite you every time!!! Prep all parts and paint them at one time! If not, when you reassemble you WILL see a color shift and will look like ****.
Direction you spray the paint, air pressure, humidity, temperature, reducer/reduction all play a major factor when spraying paint! Better off mixing color in a large mixing jug and spray all the parts from the same mix, pressure, reducer, temperature and gun on the same day then topcoat.
