A lot of my friends use the glue that you glue PVC (can't remember the name
) and even I have used it and it works good. Use 3/4 Oz cloth, sand the area to be fixed and then lay the cloth on and apply the cement but do it very sparingly as to much will melt the ABS and deform it. This method is also good for putting ABS parts together, now if I weren't having a senior moment and could remember the name of it!!!!
