Where the Suzuki stickers on my tank are white, you can see maybe a dozen little rust-colored spots under the paint. Either there have been a bunch of tiny dings, like getting nicked with something sharp, which poked a tiny hole in the clearcoat and rusted; or else they are rusting from the inside. I can feel a little bump on each rust-colored pinprick; either that is the damage to the paint from the outside, or else it is the "bullseye" bulge from the rust spot coming out.
Any guesses which it is?
Wierd, perhaps the stickers didn't agree with the paint or the clearcoat?
