so, this just pretty much just let epoxy, bondo, or ABS cement right? If not whats the difference.
No there is a huge difference between all three.
There is no such thing as just "epoxy". Epoxy has a resin and a hardener. The resin is different depending on what the manufacturer decides he wants to bond. So you have epoxy made for wood, made for metal, made for plastic, etc.
The epoxy I use is specifically designed to bond to plastic, flex easily without cracking , and withstand pretty high temps.
JBWeld on the other hand is designed to bond to metal.
Now Abs cement is used to "melt" or "fuse" together abs plastics. It actually does melt to the plastic and thus fuses it together permanently. The problem with it is that when it dries, the acetone in it dries out leaving airholes. Thus it can be used to melt the plastic together but it shouldn't be used to fill large gaps and it's not meant to be sanded and painted.
Bondo is sort of like epoxy but it is more of a two part putty. It is used mainly to adhere to metal, but it will adhere to plastic. Bondo's problem is that it doesn't have a flex agent in it so it will crack when flexed or stressed.
