How did you wash it?? washing machines will do bad work to it.. you should always rinse it off and let it drip dry and air dry out of the sun.. unless it was in fresh water then just hang it up to dry..
As far as the gaskets. get some 303 aerospace protectant, it will protect the latex gaskets from getting cracked and help them with the seal.
Don't know anything about reed drytops so i can't help you there.. do a thorough inspection of your gaskets to see if you can spot problems?
