    Is the plastic bumper primed? if so there is no need to apply ad. pro. just lightly sand with 800 or equivlant and apply sealer with a flexable additive/base/clear.
    If the plastic bumper is just bare plastic it will need to be first cleaned with a plastic cleaner to remove any release agent from the mould it was made in. Sand the bumper with 800 or equilvant than apply a light coat of adhesion promoter,no need to sand it just let flash for 10 mins apply a sealer with flex add/base/clear
