these would be safer.. 3M is ok... alot like ScratchX. try to see and gauge the depth of the scratch. if you can feel it with your fingernail, chances are, that scratch is pretty deep already. hopefully, it didn't go all the way through the clearcoat. make sure to work in the product and, rewax the affected part afterwards.

personally, don't go for cleaner wax muna. just maintain your new ride (what you got is good already)
