I agree with that sequence and method. couple coats of protan on Thursday if you can, and sleep with it on. Shower in the morning on Friday, no soap just towel dry lightly.
Then use Jan tana high definition color over the top, 2 coats. It is darker then ProTan in my opinion. Maybe a touch-up in the morning on Saturday.
I have been using the Jan Tana high Def Glaze in place of oil. It goes on very easy and dries out but still gives that glossy look under the lights.
Good luck
