I use the thin silver tape too. I think it works good for protecting paint AND works good for deflecting heat from your exhaust pipe. First body I did without silver tape there the heat from the exhaust kinda melted/wrinkled. So far, the tape has prevented that. I just put it on the inside of the body where it looks like it might rub (i.e. bottom edge, servo horns, body posts) Make sure you get the right kind of silver tape that sticks really good. Its kind of expensive, but then again, it will last you a looooong time, I use REAL aluminum duct tape. Not the kind you find next to the Red-neck grey duct tape, the kind you find at Lowes or Home Depo next to home vent ducting. Its like $7 a roll.
