I don't want any dust particles on it at all, just dust it up very well using a stiff brush. This is where it's going to be essential to have a knife, a sharp knife to cut the edges. I don't want to get to the white and if I get to the white when I pull back my masking you're going to see white, so I'm going to make sure that none of my masking is touching the white door. It's literally going to be just a hairline above that. Now I'm just going to take this, so I'm going to take my masking now and go around the edge just like this. So again I'm using Frog tape because I don't want anything to bleed under this tape. Now what happens if there's a bit of wind, which is where this could whip around and hit the top of your door. So I'm always going to tack this
