Hello, I mixed up the posted filler recipe but replaced the volume of silica with a matching volume of glass micro balloons. Everything seemed to go on ok, though it seemed a little thin- I should have held off on the paint thinner. I have done another boat with the silica filler but I remember it being a bit thicker. Problem is that my stem seams are not getting covered very much and I am continuing to add layers. I had to mix a second, half batch of filler and I used my 325 mesh silica in the recipe. Still thin. I’m out of silica at this point, maybe I can add some micro balloons and increase the filler body a bunch to a putty and slather it on the stems? I also have epoxy filling silica but that is really fine stuff. am I going to have a flaky mess?
