"many very light coats"

My DuPont AND my PPG clear directions both say 'two medium
wet coats, 15~20 minutes between coats'. What clear are you
shooting?

Rustoleum which was recommended by the local car painter.
It doesn't specify the number of coats but says that either respray
after 20 minutes or after 48 hours. On the Pinarello when I tried
two coats with 20 minutes between it grew wavy.

For once Sparky has something right. Many light coats with a few coats of clear is how custom painters get that 'Deep' look. I had my first racing bike refinished by a custom auto painter with a candy apple red. The first coat over the primer was so light it seemed link it only tinted the primer. I don't remember how many coats he ended up using, but the entire process took about a week.
