Glue for LGB plastic

Ive spun this post off from the thread on bashing a 1:20 flatcar. Anyone know a good solvent cement that works with whatever kind of plastic that LGB makes their rolling stock from? Ive tried all the solvents I have handy, and they dont even dent them. Goop and Epoxy join, but dont have much holding strength, since the plastic is so smooth it can’t get a purchase.

Anyone?
