Finish the painting process with 2-3 coats of shiny protective finish in clear satin. Don't sand in between coats with this step. As you add a coat onto another, the more shiny and less matte it becomes.
Wait the full dry time that's suggested between coats without sanding between. Make sure to wait. My piano has been in the garage for weeks!
Your piano's ready to bring inside! Remove all the tape and make sure it's good and dry.
This bright yellow piano is now my favorite accent piece in my house. It's so shiny, new and smooth. I absolutely love it. I even showed someone and they joked that they wanted to take their senior pictures next to this bad boy (see, I told you it was good).
