Call me paranoid, but I believe stickers of drum gear, tools, etc. are potential advertisements for thieves. Same philosophy about not putting a Harley Davidson logo or sticker on an enclosed trailer.
I have 1 old hardware case that is for collecting stickers. Everything else collects only scuffs and scratches.
Was behind a vehicle the other day. It had drum stickers on the back window. Lead me almost all the way home. I now know where a house with drums lives. If I wasn't honest, they could have a problem. Don't sticker your cars!
