Short of taking a trip to a store check around your home.
Wash it down with white vinegar and then rinse in cold water.
Spray wheel cleaner will also do a good etch. Rinse quickly and thoroughly.
Then use a sandable primer if there are imperfections that can be block
sanded out.
Be sure the primer and paint are compatible, dont go mixing lacquer and
enamel. Read instructions, use a primer sealer if required.
Lacquer and water based paints have the least knick resistance, 2 stage
automotive is the best short of powder coating or an epoxy. Lots of cheap
rattle can spray paints have poor UV resistance.
