'Welcome To The Madness' known as replicar ownership!
Most SOCers don't plan to, or intentionally drive in inclement weather, but sometimes it happens (scorching sun, rain & hail). Like any other weather experience driving these cars, you just deal with it as best you can with hats, 3M Blue painters' tape, tarps and what not.
Wishing you many enjoyable miles of top-down driving and viewing the road through a Speedster windshield.
