If it were me I'd use Sem Trim black in a rattle can or a quart mix can. You WILL get the result your asking about and it'll sand back off easy as if it were a guide coat...Use laquer thinner 1-1 if useing the mix can.
I would only recomend something if I have done it myself.
If this turns into a "cheaper way " thread I can't help you there. I don't belive in cheap.
