Thought it was going to be costly, but I took it to a Plastic Welders who primarily do underground drainage

They have repaired (plastic welded) my original 22B spoiler, 4 inch long crack one side, and a 2 inch crack the other side

They did it this morning, total cost 20 quid !!!

absolute bargain if you ask me

Most bodyshop places I took it to wouldnt touch it, as they could only do fibreglass/resin repairs, and wouldnt offer any gaurantee

this place i went to this morning have done bike fairings, car bumpers etc, and no one has ever gone back to complain !

Nice one
