If you want clean 2-tone paint lines, spray the smaller area first. It gives you better control, makes masking easier, and helps keep the paint line sharp when you reverse mask for the second color.
Most guys think about color first. Light color first. Dark color first. Top first. Bottom first.
That is not the main thing I care about.
What matters is control. On a 2-tone panel, I want the smaller area sprayed first because it gives me the cleanest shot at controlling the edge.
When you spray the smaller section first, you are not fighting the whole panel. You have less area to mask, less area to protect, and less chance of overspray getting where it does not belong.
Once that first color is down, you can unmask it, reverse mask the panel, and spray the second color with a lot more control.
That is how you get a crisp line instead of a rough edge that needs to be fixed later.
The tape line is not magic. It comes from prep, tape choice, pressure, and how you remove the tape.
I like using 3M fine line tape for the color break because it lays cleaner than regular masking tape and gives you a sharper edge.
Then I protect the rest of the panel with 3M Scotchblok masking paper and quality 3M automotive masking tape.
If you spray the larger area first, now you have more surface to protect when you come back for the smaller section.
That means more masking, more chance of bleed, and more chances to screw up the line.
Bad 2-tone lines usually do not come from bad paint. They come from bad order and sloppy masking.
If you want a clean 2-tone paint line, spray the smaller area first. Always.
Get the edge controlled, reverse mask it clean, then spray the larger area. That is the difference between a line that looks finished and one that looks like it needs to be fixed.
