I use 9460F, you guys might want to try it. It is grey in color and dries much faster than 9462. If I am not mistaken it is stronger as well.

It does not sand as well. I actually use 9462 to mold in hatches and the like. Once it is really dry it is relatively easy to sand and can keep a sharp edge on a hatch.

BTW I don't know diddly about polyester I was just mentioning the different kinds of Hysol (now Loctite)
