It broke in two pieces. Since polyester resin as a repair medium is not very strong, can epoxy be sued with better, stronger results?

Unfortunately though, any resin you use is going to show a line. Author Posts Viewing 1 reply thread The topic ‘Using epoxy resin for a repair’ is closed to new replies.
