Question for you RC painters

[magman]

Starting painting a lot of rc bodies for friends lately and I am using liquid mask to mask body. I was wondering if I can first apply the paper window mask that comes with the body and then apply the liquid mask around the edges to help give the edges a crisper look. Haven't tried this yet, but was curious if anyone had. My hands do shake a bit unfortunately and my paint edges are not as crisp as I want
