Is it worth trying to repair a crack roughly 15 mm from the plug hole in
a fibreglass bath?

I've seen various kits of the web which claim to be miraculous! Or
could use car bodywork resin - as in one of the Isopon kits - to fill
the crack?

It only has to last less than a year as the bathroom is due to be
gutted. Thus, waterproofing is the only aim not aesthetic perfection.


TIA
