So I stayed off the sodden trails on the weekend and instead headed out on the road. I've got a 6 year old "waterproof" jacket.

Netti with Entrant that was meant to be like goretex. Anyway riding on the weekend my jacket just became wet and slowly seaped through. My partners jacket is the same model but only two years old and the water was beading straight off hers.

This is the jacket http://www.bicyclehq.com.au/clothing/jackets-and...

Anyone had any luck with waterproofing treatments? Any recommendations?
