I have a few older (5+ years) but not excessively used "waterproof" breathable clothing items (pants, jackets), that are not waterproof in high-abrasion areas such as knees, shoulders, crotch.
Is there a good way of waterproofing these areas?
Since these areas will quickly wet out regardless of DWR status, I'm ok with losing breathability in these areas.
I was thinking of maybe applying diluted silicone locally - either as spray or caulking+mineral spirits. Would that work?
Other solutions are welcome too of course.
