Stupid question i know but i just brought a new wiper for the tintop with a spoiler (only £1 more that without )
Which way up does the spoiler go? I would have thought it would be on the top but my mum has one and hers is at the bottom (nearest the bonnet).

Spoiler on the bottom to allow the air to be blown over the wiper if that makes sense

Ok cheers

I bought similar for my tintop. Spoiler doesnt fit wiper arm and affects the sweep. Bloody bosch crap.
