I had to wait a week to get the proseal to "glue" the trailing edge together. I stoped at the local metal supply and the man there gave me a 50" piece of aluminum angle to hold the edge straight. I had to pre drill all 46 holes to line up with the skin. I mixed the proseal by hand and applied it with a popsickle stick. I will get a dispenser before I do the fuel tanks. This stuff is nasty. I'll let it dry until after the holidays.
