*ABS Cement

::Use ABS plumbing cement with low VOCs (volatile organic compounds) . This is used as a sort of "bondo" to fill in cracks and deformations in the bodywork. Unlike bondo, the ABS cement will melt and fuse with the ABS bodywork, making a uniform repair material.

Home Depot or anywhere that sells plumbing supplies usually carries something like [http://www.amazon.com/Low-VOC-ABS-Cement-Black/dp/B000UG3GJQ Oatey Low VOC ABS Cement].

Next is a crack on the same piece.

The lower end of this piece shattered, and left a fracture running up it. The crack is a good candidate for repair.

The lines show the fracture ran along the edge, which was reconstituted using ABS cement. As a result, the rounded edge of that corner is gone. It's now a sharp edge, which can easily go unnoticed. The ~~Orange~~ is also significant. That section was gone. Entirely gone. It was rebuilt by making a thin ABS layer, then rebuilding the surface. The rebuilt section was less than perfect, and cracked while back on the bike. This was because the shape it solidified into was not the same as the original shape. After welding the new crack to relieve the stress, it has been doing fine.
