Sand your piece! I prefer to use an orbital sander for larger areas. Use a hand sander or sanding block on the harder to reach areas. Wash your piece down. I use sugar soap for this step. Wipe clean with a clean cloth or rag. First coat of paint- I used Corinth Blue from General Finishes ❤️ First coat on and let dry... look at that colour and so smooth🙌 Apply second coat once you have given first adequate time to dry. After three coats I applied the unicorn spit with a cloth and concentrated on highlighting areas.
