If it is a basecoat/clearcoat paint (urethane) used on the bikes then you'll need to mix the pigment (base) 50/50 (usually) with the proper reducer. Spray that over the primered area, then after 30 minutes and within 24 hours you have to apply the clearcoat. It is best to stay with a single mfg. for primer, base and clear (and for the reducer for the base).
