The last time I used fibreglass was to seal the bottom of the ABS plastic air inlet moulding after removing the part that sucked air from back of engine/bellhousing doh Obviously the area was cleaned first but the resin stuck extremely well after roughing the plastic up a bit. Finished item below.

Note to save all this work several folk including myself have made or had made alternative tool trays so may have an original lying around they are willing to part with. Unfortunately I sold mine.
