How Long Can You Wait To Paint Over 7220?

I'm getting ready to paint my interior of my RV8 and am using NAPA 7220 and Rustoleum Hammered as a top coat. It will take some time to get the whole inside primed and I might have to wait untill the following weekend to do the paint. Will I have to scuff the primer if I wait a week to paint?
 
My experience with the napa is no worry about time to top coat, but, most rattle can paint will lift existing top coat, so if you prime, paint any time, but then spray more paint ontop of rattle can paint after it cures like a day or more, it will be bad. Epoxy primer and all the other real paint, another story. and I would not use any rattle can primer or paint in any high traffic areas, seats, floors ect. it will chip, lift easy
