Application Conditions for Basecoat/Clearcoat Systems


For basecoat/clearcoat systems, apply the basecoat according to manufacturer's instructions. After the basecoat passes inspection and is ready for the clearcoat application, apply Sur-Prep® AP-1 over the basecoat following the applications steps in this TDS. Allow the Sur-Prep® AP-1 film to dry for at least 30 minutes and then mix and apply the clearcoat. Allow Aerodur 3001 to dry for a minimum of 2 hours before applying Sur-Prep® AP-1 to it. Lastly, allow Aerodur 3001 Special Effects basecoat to dry for a minimum of 3 hours before applying Sur-Prep® AP-1 to it.


Note: If the basecoat is allowed to cure beyond the manufacturer's recommended cure conditions, Sur-Prep® AP-1 cannot be used to reactivate the basecoat. The basecoat will need to be scuff sanded and then re-applied. Moreover, Sur-Prep® AP-1 will need to be applied after the basecoat cures. Sur-Prep® AP-1 does not extend the overcoat time for Aerodur 3002. Aerodur 3002 must be sanded with abrasive paper or pad before Sur-Prep® AP-1 can be applied to it.
