I'm looking for advice and feedback on this touch up. It's my second one of these carbon fiber fabric repairs, my first turned out much better. I used the powdered pigments to match the color of the original wood, which was exposed along the margins of my repair, then I used glass slides to match the color of the lacquer. I then used The Mohawk brush tip marker, which I don't think I'll use again because I couldn't get straight lines. The graining pen along a straight edge worked much better the prior one. My main concern is where the new color and the old cover overlap at the transitions. Does anybody have advice, or what would you have done differently? Seems impossible to paint up to a color coat that doesn't fade in gradually. What tint should I have added or left out to get the color more spot on? Thanks looths.
