cover keep a white towel on top and try to not let the sun hit it, like an outside cover. Not much else. I eventually got a vintage dashes for my 75, looks great, car is mostly garaged, if I do leave it out I generally will try to leave somewhere safe and keep the windows cracked open to let the heat out, this is on top of a white towel. While driving I have a white towel covered with a black towel to keep the glare down.
