Very good site, I haven't seen that one before. I do about the same thing but on coat 4&5 I mix my poly about 50/50 with baby powder to fill the weave. Most of the powder is sanded off so there is no real extra weight added and by coat #4 the weave is pretty much filled. I used the laquer based poly and the smell/fumes about knocked me over so I'm going to go with the water based poly this time. I also used the 1/2 oz glass just to save that little extra bit of weight. The glassing/paint really helps out on hanger rash and there are no covering bubbles or sags when sitting out in the hot sun. Takes me a lot longer to glass and paint then to cover but the finished product was well worth the extra time.
