Having spent 18 months restoring a big arched Twin Cam shell, we sent it to SPL for acid dipping. It came back with a dented roof, dented front wing and a bloody great crease in the door. Not to mention drilling it in the wrong place to let air out and subsequently having a big patch in the top of the rear wheelarches that isn`t treated. Not best pleased. Their answer is to knock a few quid off on the next shell we take. So having another shell to do, is there anywhere else that can do this and if so are they any good?
