ive got new R3R, just taken off all the factory sticker and rear seat, there are blemishes on the matt black paint, normally these would polish out no problem, but not sure about using t-cut on new matt black paint work?
Well done and welcome to the forum.
I too don't have a definitive answer but know on Street Triple forums the owners find Mr Sheen or a similar furniture polish good for removing finger prints and marks without adding gloss. Might be worth a try?
Bloke that owns a new R3R here in town removed his sticker as well .. guess he had a similar problem as he's replaced it with gloss black sticker. Don't look to bad actually.
