I assume you really don’t mean that. Bumper stickers can be pain to remove. I would never get one.
For ones I really like, I buy HVAC register magnetic covers, affix the bumper stickers to them, and trim down the magnet.
Anyone else remember going to major attractions in the 60’s and returning to find their bumper sticker affixed to your car?
Made my dad angry, said he’d never be back to Stone Mountain, and we never did.
