We keep getting threats of hail here in St Louis and I have my SSRs outside. I will put a nice heavy layer of moving blankets on them, then the factory cover, then put an out door rated cover over the top of that. So far there hasn't been any hail hit where I am but you never know when it will hit and it can hit one area and 3 block away only have rain. The 05 right now has stayed under cover while I am redoing the front end but the 04 gets driven, so as soon as the weather threat is over it gets the covers pulled off.
