Proposed Response Text:

thank you for your inquiry.

Our two-stage/three-stage paint code identifications are based on the consensus methods outlined by the major refinish suppliers.  

Some paint lines may offer a three stage solution for a widely accepted two stage color in order to achieve better results.

Users may encounter situations where the paint line being used identifies a color as three stage but we do not.
We recommend deferring to the requirements and guidelines of the specific refinish line utilized for the repair.
