I left the fill coats on mine until after the whole boat was glassed. My main area of concern was where the deck glass overlaps onto the hull. It's a stronger lighter joint if the fill coat is done after the overlap.

Thanks Laszlo,

That confirms what I was thinking. if you do the hull and then the fill coats, then the deck and it's fill coats. Then you have a 3 inch section that has 2 layers of glass with way to many fill coats and that's just wasted epoxy and weight without gaining any more strength.

I agree with Laszlo. I did it the other way on my wd10, all hull then deck. I have a wd12d being delivered and i will do both hull and deck , then fill the weave on this one

Having just sanded through 98% of the fill coats from the overlap on my C16, I'd say go ahead and glass it all before putting down more epoxy.  In retrospect, I wish I had done it!
