How can I prevent scratches from satellite radio antenna?

[07bsmcrewmax]

I have had satellite radio for a few months. Everytime I wash my truck, I move the antenna to wash underneath. I have noticed that some scathes are starting to show. Any way to prevent this? I thought about buying some of that clear bra stuff. Where can I get a ptece that small and is it removable down the road?

Go to a local sign shop and ask for a piece of clear vinyl. If they hit ya up for a couple bucks, its well worth it.....

I wonder if it`s possible to get silicone in sheet form, sorta like the stuff they use for the Water Blade. If everything was completely clean, that should be fairly safe.
