Hi Jim,
as its swirl free lime prime by hand then white diamond if you feel you need it but tbh it wont add anything then either Supernatural or Supernatural hybrid or megs 16 or colli 476/845 over the top or go for a couple of layers of sealant,
silvers/whites look very good with just sealants or the waxes ive stated, layering will help bump up the finish and ensure even coverage.
