Ok, here is my dilemma.
I recently bought some leather motorcycle gloves on eBay that were reportedly waterproof. My plan was to use these gloves for track day, summer, winter, and everything in between. Needless to say, I found out the hard way the item was misrepresented. Trust me when I say wet, soaked leather against your skin is not fun. Now, I'm stuck with a nice pair of gloves unfit for rain.
Please help me decide by picking from one of the following choices:
A) buy a dedicated pair of waterproof gloves to carry with me at all times (i.e. Teknic Cyclone Waterproof gloves (http://www.teknicgear.com/pages/collections/textile/glove_cyclone.html))
B) Buy a latex rubber or polypropylene gloves to wear underneath (Click here (http://www.apsltd.com/Tree/d3000/e1728.asp) & scroll down to the bottom to see what I mean)
C) Buy waterproof glove liners from SealSkinz (http://www.danalco.com/htmls/products/products.shtml)
D) Prune hands are actually good for the skin
E) None of the above
(If you chose E, then throw me a bone, please?!?!)
After getting through last winter with only my one pair of non-waterproof (actually vented!) gloves :o ,
I'm now waiting for delivery of a pair of these:

Waterproof, armored plus Thinsulate(tm) :) . I'll let you know what I think. See

I suggest getting the rainproof cover mitts to go over the gloves you already have. Liners will still get you wet leather gloves (and water is not a good insulator, so your hands will still get cold).
I have the TourMaster Cold Front Carbon gloves and they're great! In addition, I add Thinsulate glove liners as well for when it gets even colder.
I second the good advice from Scratch. Overmitts are the best way to go. Ski-overmitts if you can get them. As well as keeping the wet off from any pair of gloves worn inside them, they will also keep your hands very much warmer by keeping the wind off your gloves. I commute every day to work through the winter, and never have a problem with cold or wet hands in freezing rain or temperatures around -5C.
I've read that you can apply a waterproofing product called Nikwax to leather. I bought some and put it on my boots and gloves (I wear a textile jacket). I haven't been caught in the rain yet, so I can't tell you how well they work. It costs like $7.00 a bottle, and looks to last a long time.
