Still trying to get started on Skeezik, kitchen still not done. As for the filler ,I found a new material to replace the silica in the home made filler.I have the white lead to make it with and went to Fiberglass Coatings today and they suggested using what they use as a filler without a lot of weight.It is called Fumbed Silica a very fine powder 1/10 the weight of 340 silica and looks a lot like talc powder. What do you think? Griffing
