And who came up with the idea to use 5W20 in our cars? It's hard to find that stuff. And NO before anybody asks I use PENZOIL not "royal purple".
I like the umbrella idea, also you can buy one of those fold-able canvases, and it'll cover most of you car, or just get 2... I have one its like 10x10x7 or 8 ft tall... Pretty good for covering sun and rain... and pretty cheap
