Uhmmm, I have some nuts/bolts I paint yellow after a full restoration project,
so when the customer comes back complaining the carbs aren't sync ed I can
catch him/her, and point out if they want me to fix it AGAIN, beause the screws/;nuts/bolts
were retourqued, touched, moved,
the normal
shop rate applies starting 15 minutes ago.
Ergo, go with yellow nuts. Red looks nasty and most women will find this to be
a reason to go out with " numbnuts over there " instead of you.
