Depending where you live & if you know any I would take your bike to a auto re-spray shop & ask them what they would use or recommend, there are several very good "cutting polishes / cutting compounds" but rather than make it worse & buy the wrong thing I would try this route 1st.

Yes Scotch-brite pads are not for cleaning paint work or even crome, or ally rims, handlebars etc, they simply will scratch
