This is too simple a topic for this board but does not fit as well on any of the others.
I have been using JB Weld for a few years and it has done fairly well in terms of strength for
repair and in filling in and around gaps in fabrications, etc. However the stuff does not lend
itself to being smoothed out or "mini-troweled" to give it a semi-finished appearance which can
then be sanded or ground. I have tried waiting a little while before attempting to work it but that
tends to shift a mound over in direction of tooling. In that case, when sanding the dried JB Weld you
have to take so much off to remove ledges at the edge of applied material you have possibly removed
enough to compromise the application. If you try to work it wet, you get swirls when you lift the
tool (beveled stick) like on top of an ice cream cone. Does anyone know of an epoxy with good strength characteristics that can be worked towards a smooth surface in preparation for final sanding and paint?
