However if you leave the sail flat on the ground in the rain it will start to absorb water. Try keeping the sail upright so that the water tends run off.
Older polyester sails that have seen a lot of use, tend to loose there water repellent coating and will absorb some water quicker.
Now nylon sails(pre-1998) will tend to absorb water earlier in their age and get a bit heavier then polyester sails.
I personally, would not want to put a extra water repellent on my sail.

Nylon will absorb quite a bit of water (and shrink when it does). It also takes quite a while for the nylon to release that moisture. For a nylon sail, adding a water-proofing might be worthwhile.
If the sail comes with some kind of air barrier, it might be worthwhile to renew it if it begins letting air through, as that will keep the light-air performance up to snuff. Just don't add weight for a short term benefit.
