I'm finding that it still works better than the 6 or 4 inch putty knives because it covers a larger area and lays down a smooth swath. It seems that the edges of a putty knife are my enemy, leaving little ridges in the previously spread compound, so the wider knife has fewer edges that I have to try and feather out for a given area. The smaller plastic knives that I have also seem to have a tendency to bow up in the middle slightly as I pull the compound across the deck. This leaves humps that will have to be sanded out later. So I still have to contend with a few ridges with the big knife, but it doesn't bow and lays down a nice flat spread. Unfortunately, the remaining aft section has some really tight spots that I will probably have to use a smaller knife on, but we'll see when I get there.
I think that I will have just enough time to get the second coat on the aft deck and maybe a few spot fills before the cold weather keeps me from doing anymore epoxy work for the season.
