Can anyone help me with this. I bought a pair of wings for my Escort made by Embo. The black paint that coats them is very hard and well applied, the sticker on the wing states cataphoric which I believe to be quite a good protective paint process and it is hard to rub off. Would it be best to leave this on? I know that some of the black paint that panels come with rubs off really easy and is only for storage protection. Thanks
