making custom foam grips

[ReelSeaSick]

I am making a grip from foam that will be rings of red and blue. I am using contact cement that Clemen's custom tackle in PA said would work well. Any advice on making smooth joins. If I use the glue to the outer edge, it may be seen and if I don't use enough, there may be a slight gap between the colors. I know that I can sand it after it dries. Any advice....<br><br>Tight lines at sea, screamin kids at home!
