Park your Mav in the sun, and let the vinyl heat up. When nice and warm re-stretch it over the Velcro while it is warm and more pliable. I do 8-12 inches at a time working both sides separately.that looks great! I have the same one however I didn't install it and it is no where near as taught as yours, it sags between the supports. Looks like I need to go back and see if I can adjust it!
