You Will Need
First of all, water down your paint. I used semigloss white paint that I had left over from the trim. I watered it down to 2 parts water 1 part paint. I was worried that it would look too glossy because it was semigloss but it didn't at all.
First, sand the pallet with a medium grit sand paper. You don't want to make it smooth, you just want to remove the big splinters.
Brush on your watered down paint.
This may be hard for the perfectionists out there, but hear me out: DO NOT do a second coat. DO NOT fix anything. Once you're done just walk away. Because this isn't supposed to look pristine, it's not supposed to look perfect. It's supposed to look weathered, and that's exactly what it will look like if you follow my instructions.
