In the knowledgebase theres a article called sealing the Tbar using the sealant and clingfilm method, that sorted mine out.

Basicly you remove the roof tops and squirt some black silicone sealant

(the stuff they use to stick windscreens in) around the rubber bits where it seals with the car, squirt a gennerous amount as you can always cut any extra off, then cover the bits that you put the silicone on with cling film, then put the roof panels back on the car.

The clingfilm stops the roof sticking to the car but allows it to fill in the bits where its leaking.

leave it like that for a day, then take the tops off and remove the cling film.

Sorted!

Much cheaper than new seals!

Its worth getting one of them gun things that you put the tube of sealant in so you can control how much you squirt better, they are like
