Don,
Glad to here you took your Cobra out! (I figured you would, sooner or later)
After driving all summer, it would kill me to have to park the Cobra for the winter. If you wait for nice days up here, you loose almost half of the year.
I do manage to wash my SPF most every week, at work. You have to be very careful about not getting any water in the side curtain slides, or you either get trapped outside or inside the Cobra, depending on when the window freezes
This is a great thread, and perhaps more Cobra owners in the colder part of the country will get out at least a couple of times this winter.
Jim
