Diy marbled wine glasses Make a cool artsy goblet. Here’s how: combine water and nail polish in a mixture. Then dip a stemless wine glass into the mixture. Spray the glass with clear sealant to allow the nail polish to set over night.
use for top coat/sealant over chalk paint, instead of wax, on large pieces. Pretty sure this is what you want as it acts as a water barrier like a oil based finish, but you can still wipe it down with water like a water based finish.
