Let your enamel cure for a couple of weeks and then you can carefully wet sand with 1000 and 1200 gt sandpaper (available at any automotive store that sell finishing supplies) on a flexible backer pad. Work slowly, trying to just remove the high spots. Finish with a buffing/polishing compound to restore the shine. Lightly polish the surrounding tubing so that you don't have one spot shinier than the rest and finish with an automotive wax. If you work carefully, even paint that doesn't match perfectly will blend into the surrounding paint enough that it won't be obvious from normal viewing distance of a few feet.

Even if your enamel feels bone dry, don't rush it, give it a couple weeks to cure, longer in cool/damp weather. If it is really hot, dry and sunny you can maybe go a little sooner.
