without which the whole thing is pretty much a chuck out.

Model is discontinued, parts are unavailable so I am repairing again.

Previously repaired some broken polystyrene parts by patching with
polystyrene from CD boxes and plumbers' solvent adhesive. These repairs were
only partly successful, having lasted more than twelve months the
polystyrene has become crazed and crumbly and cracks are opening up again..

I was proposing to repair this time with epoxy resin in conjunction with
wood stifeners, plastic patches or maybe glass mat.

Will epoxy resin soften and destroy the polystyrene I am trying to repair?
Is there a better way to repair these things?

I know it's polystyrene because it is marked PS.

Whichever you do, drill the ends of any cracks to prevent propagation
before you start.

There are two types of GRP resins. Polyurethene based (the cheap
ones) and epoxy based ones (similar to Araldite) if that helps.

How about the solvent glue sold to glue ABS/PVC pipes? (No experience
of it in your situation.)
