Would it damage the paint at all if I put a PH sticker directly onto the bodywork, as opposed to the window? It's one of the vinyl ones where you peel both sides of paper away to leave just the smiley & cross pistons. Ta.
I'll assume its the same as the stickers you get from Brands hatch etc, my brother managed to remove one of those no problem. Think you just need some brake cleaner / intensive tar remover to clean it up once its off.
Hasn't damaged any of the cars I've put them on (and that includes putting one of the enormous smileys across the bonnet of a Mini). Bit of a gentle pry off and perhaps a dab of bug and tar remover works fine.
