I used microballoons by mistake to thicken the epoxy used in the scarf joints and I am concerned about the strength of the joint. (I thought microballoons and cab-o-sil were the same thing.)
I have now read that microballoons are not to be used in structural joints. What should I do? Should I be safe and cut out the scarfs and rescarf? Or will the joint be OK. Maybe I can strengthen it another way.
I used about 50% epoxy to 50% microballoons by volume in the mix.
