the balancing machine will have several modes, starting with the steel wheel one for knock on weights with the weights furthest apart, then for alloys, various positions depending on the style of the wheel, ending up with just one weight in the middle, using stick on weights.
i’d leave it myself, doesn’t look too bad, if the paint has only just been done peeling the old weight off will probably pull the new paint with it because if wont have hardened yet, and it wont be as good as factory paint anyway.
i always put a bit of silver gaffa tape on the weights as a belts a braces type of thing
