An EXCITING...New Evaporative Cooler Cover?

Not that exciting, but maybe useful for someone else with the same issue.

You have an evaporative cooler, but you see that cover at your local hardware store, and the mustardy baby diaper color just isn't what you'd choose to put on a highly visible item on the top of your house.

Marine-grade canvas, in customizable colors. Pretty sweet. About double the cost of a normal cover; but having owned two of the old ones, I can tell you the one I have is going to last a LONG time while the others were lucky to make it through a season or two without ripping.
