Here is one I'll brag about but credit has to go to my friend John who helped me restore my car. (He passed away this January , severe diabetic complications). It make a very tedious job very easy and works fantastic! Use a srynge with a semigloss paint and lay down the black lines with it going slowly. Make sure the part you are doing is level. and let the paint dry. I did my grill shells, taillight housings, upper and lower trunk trim , my Hood Inserts and my formula S badges using this method. Worked flawlessly!!
