Can you tell me what number you started with and your method please
Could you get it as close to perfect as your are prepared to accept and then clear coat it or clear wrap it? There are some very decent clear wraps available these days that are applied to very expensive vehicles that you wouldn't know were there!
I used to use the blue painter's tape to mask the edge of the vinyl, but i've stopped doing that and just buff right on to it (with the Cyclo polisher). A wipe with naptha afterwards cleans up any residue that gets left on the vinyl, and no issues with edges lifting. I believe it's 3M 1080 vinyl.Is there a concern with future buffing near the edges of the wrap?
