I have an 87 Conquest that I just got running that is about to be kept outside so the wife can have her spot back ha. I need to get a good outdoor cover for it, any recommendations?

Also, it has been off the road about 2 years, I have had it since June. It looks like when it broke down that it had been driven in the rain and never washed. When I got it over to the house a few months ago my son and I gave it a good hand wash, and it still has the dirt patterns of being driven in the rain? Its shiny but you can still see where the splashes were and the dirty mist etc. What would be a good method to getting that off? It looks great from the right angle, and from the wrong angle you can see the mess.
