Removed some of the existing furniture so I could get to the windows and started spraying them.
I just got a bog standard tin of Gloss Black car touch up paint, cleaned the windows then gave a very thin coat. Once this had dried (about 15 minutes) I put a thicker coat on and from the outside it looks fantastic 🙂
I will post pictures next time we get some sun and can get my camera out again.
It is using about 250-300ml per window in case you were wondering how much it takes.
