ABS is usually "welded" using a hot air "torch" and ABS rod. Such rigs
are available for about $30 from Harbor Freight. I have also repaired it
using a 25 watt soldering iron.

I have a 1975 Snark Sunflower. It has an ABS shell over the styrofoam.
I need to repair the shell -- it has cracks in it, and nothing's
missing. Other than duct tape and paint, what's a good idea? Isn't
there a chemical I can use to weld it back together?

Thanks.
