My personal opinion is that the only cover you need is two coats of wax every 4 months or so.
My black factory paint is still black after 17 years because of this. I've owned it since early 2002.
I see you are in SF. If you cover it there will be salt and crud that will get under the cover and the winds will slowly scratch away the clear coat.
Wax will protect against bird crap. My truck has been a victim of birds. I've lived within 10 miles of the ocean since 2002 and I've had the same method the whole time.
OP - you think the cover will survive high winds or will you use larger anchors? I've looked at some of those but am afraid it won't hold up in a 70-80 mph downdrafts we have regularly in my area.
car covers are for german sportscars...
Weird coincidence - one of the guys I work with just got a new pair of climbing shoes delivered from back country today - and I'm thinking damn that logo looks familiar..
