Wes- I just did 2 coamings on my double and had no problems having it lay down. Make sure to cut the glass on the bias (mine was 30 degrees) and to radius the bottom where the coaming meets the deck so you can wrap the cloth under the deck. Charles was right on with wetting the inside of the coaming to hold it in place as you smooth it down as you go around. Use a brush to apply the epoxy and smooth into place. Use a squeege to smooth out and gloved finger worked very well to get the underside of the lip.

First coaming was 1 piece and a little unwieldy and the second (2 pieces) had no visible traces of the 2" overlap with the second seam. You're going to have 1 seam at least anyway you look at it. Two isn't any different. Don't starve the glass. I cut my glass 7" wide as it narrows as you stretch it when cut on the bias.

Someones tip on freezing an epoxied brush in a zip lock bag to use later, worked like a charm. At least for 1 more use anyway.

Although it was quite time consuming, it wasn't really that difficult.

Good Luck - DAVE
