Use either a good automotive primer, or my favorite Tamiya. Clear can be a tricky thing, the wrong one will ruin your day. Testors has some enamel clear, or if you use light coats you can use their laquer clear. Those cheap paints in hardware or big box stores are a disaster waiting to happen on models or trains. Always wait more than 3 days to recoat, or clear coat enamels. The smell test is useful here. I like Tamiya clear coat, never an issue with them as they are a synthetic laquer. Best NOT to cear coat enamel.
