A trick I just came up with on this build for painted pinstripes. Im sure many have done it. I just cant work a stripe brush period. Constantly amazed at those that can. Any way, common paint pens from Walmart @ $2 are used. Have many colors in solids and metallics. Simply run your tape lines, then carefully drag the pen down the tape edge. Plastic tape is really a must, or you will get bleed under on the solids, the mets are not bad. What really works well is 1/8 vinyl pinstripe tape as it will make almost any bend required, and is paint tight. The thickness of the tape and the size of the pens tip determines the stripe size. I wanted stripes about 1/16 so the fine points worked out to about that. The paint is pretty durable once dry, and stands up to clear coating. A couple of light coats first to seal it down before really flowing it to it. The stripes in the pics were quickly done and arent as nice as on a painted surface, but it gets the idea across.
