Hi all, I am prepping my ’68 Nova for paint. I want to do Auto Air’s Flame Red semi-opaque with Eastwood’s premium clearcoat. My question is this: I want to put two black stripes down the middlle of the car. Should I use adhesive-backed vinyl, or would it be better to paint them on? If painting, should I tape off the primer where the stripes will be or just spray them over the basecoat? If using vinyl, should they go over or under the clearcoat? Does anyone know of an easy way to lay the stripes out straight?
