You've already done it, and it won't hurt anything. But I want to put this out there for next time, and/or other readers: You can spot prime and still basecoat an entire panel if desired. Base coat will adhere well to the fairly fresh clear. Use of a full coat of something on the whole panel before base is probably best done with epoxy mixed as sealer instead of three full coats of unreduced epoxy. Such a technique uses less material, costs less, takes less labor (mostly sanding labor), and minimizes excessive film build.
