I don't know what you guts are doing to your rain jackets but mine is as good, if not better than new after cleaning it with Granger's Performance Cleaner and reproofing with Superpruf.
Nikwax Tech Wash and TX spray are also excellent. (I've tried Rapha's version which also works but I think it's just rebranded Granger's but pricier.)
Most treatments last for between 20 and 30 hours of use.
