I've never understood these things, unless maybe you are driving to a car show where it is going on display and you want your motor to be protected whilst you get there.
It reminds me of my mate's mum who insisted on keeping the clear protective plastic wrap covers on her dining room chairs to stop them wearing!!

Really what is the point of trying to protect something nice looking if the protector makes the thing look nasty, and possibly feel nasty! Completely bizzare!
