Be careful unblocking the sun roof drains. You could knock the tubes off, good idea to clean them out though. If you want to check for boot leaks have one inside the closed boot and one outside with a hose and start from the lower surfaces and work your way up. Take all the affected trim out and dry it fully - it will promote rust if left damp. I had to do my lamp gaskets too.
Good - Fast - Cheap: Pick any two.

I've just changed my wiper blades and now my reverse lights don't work. Should I change my fuel pump relay?
