My first time using micro balloons and epoxy mix. I used 30 min epoxy and found I had to mix the balloons a little thicker and also keep flipping the fuse so it wouldn't run and puddle for 30 minutes. I think next time I will try 5 min epoxy, especially for a non structural fill as it will set faster and wont run. I just need to cut the tubes and sand smooth now.
