Fantastic responses! Thanks so much to everyone!

Good to hear about avoiding background stain. I'll avoid it.

And Noseoil, I thought I'd give this a PMK a try, and maybe next time compare it to Sandy's formula (flaking out on name). Too many developers lol

David, so you put the used w. the new to avoid having 4 bottles? I was going to have a new/used fix and rotate.

Thanks again,
