No suggestions, unfortunately. My Gore waterproof jacket started to soak through during a ride in heavy rain last month, and my friend's Gore jacket was totally soaked as she rode longer in than me in the same storm. Another friend who commutes by bike year-round said that nothing is totally waterproof -- if you're out long enough anything will soak through.
I recently read Gore's care instructions for their jackets and was thinking of following their instructions for washing my jacket to see if it will boost the waterproof-ness.
I was chatting with someone about my jacket soaking through and he mentioned that a client of his has an Arcteryx jacket that's waterproof. Not cheap, though.
