on my mk2 i replaced the crap, flimsy scuttle panel with the 'later', thicker, better scuttle panel. with my old scuttle, i cut a section out about the size of the vent under the scuttle and siliconed it to the top to act as a kind of umbrella! then replaced the scuttle panel and tested it. works a treat, noone sees it, so thats all that matters!
