After frosting the glass I had the vinyl cut out and I accidentally put it on upside down. While taking off the vinyl it left residue. I went to wash off the residue and along came off the frosted paint. Found out that the paint does not adhere to the glass since it is a porous material. After some research I found I can paint it frosted then use a sealer to protect it.
Here is what I ended up using. I did two coats of the frosted glass letting each one sit for 24 hours. Then I did two coats of the matte finish again letting sit for 24 hours between coats.
