Update
I wanted to update this as I think it will help others. Per the responces I tried the Nikwax products. Specifically I used the Tech wash to clean my gear and the Polar guard to renew the water proofing on my sled gear. The Tech wash does quite the job. I had been washing my Army gortex for years using regular laundry soap. It had gotten dinghier with time, still didn't leak though. The tech wax cleaned it to the point it almost looks new. Same results with my riding jackets and bibs. I used the Polar Guard on my bibs as the coats hadn;t leaked yet. It is nice as you do it in the washing machine and no stink. Then low tumble dry. I haven't used the sled gear yet, however I did take it out in the rain while wearing my gortex and both garments beaded water much faster than before the treatments. I bought it at Tri State in Moscow, ID. It costs a bit, $20 bucks for both products, but at least the Tech Wash really seems to work well. You can treat about 10 items roughly. Not bad for over $800 dollars worth of gear. I will update after riding some. With a family of six riders, it helps.
