Does anyone know if the putty has solvent in it? I have used it in three kits and it has ruined all three. It melts and weakens all the plastic. Is this a fluke or should I look for an alternative?

Yup, it has toluene in it, which is a solvent that melts the plastic.  Though, if used properly, it should only melt the top surface, and then dry, in order for it to create a bond with the plastic.  Sounds like you are using way too much of the stuff, in order to fill huge gaps.  This type of putty is best used in thin layers, or for small cracks...

I would suggest fitting a styrene panel to cover the gap then puttying the seams of that instead of using lots of epoxy which could also have weight issues.
..hmm, I'm supposed to type something witty here...
