My stormtrooper jacket has provided many years of protection. Recently I noticed its water resistance seemed to be not as good as it used to be. I had already followed the cleaning instructions for rejuvenation. So I purchased the Tx product. Applied as per instructions and tumble dried on a low setting. Went out riding last Saturday in flood heavy rain. Worked a treat. I definitely noticed an improvement. Reccomend trying this if you have any good quality but old wet weather gear.
