Ok, Thanks. I will try more time. For what it's worth the second 12 hour session in the Salon UV light yesterday didn't make much of an improvement either. I'm still around a half stop slow about the same tint. Probably a logarithmic function, taking more time for the same tint reduction toward the end for a given UV flux...... Just guessing.....
