FG Marder Shell repairs

[Dreadnought]

Hi all,
I've got an FG Marder shell which is split in two places, is there a method for gluing similar plastic inside as I don't want to melt the plastic using the wrong materials?

Cheers

Shoe goo and fiberglass mat. Will be a tedious process. But should work quite nice.
