The spinrite is great. I have always like Bohning paints....be sure and dip or lay down a white base before trying to cap dip or crest.
You "don't have" to put down a base, it just makes the colors of the cresting "pop" out a bit more. I almost always use "testors" hobby paints for the cresting, then when done I go over them with a clear water based acrylic for protection. Worked well for may years.
I have that crestor plus 2 others. Use it the most. I used to dip with Fletch Laq as well. These days I cheat and use wraps. Plain ones I get from One Stringer or ones I cut from vinyl paper I buy at Michaels. Presently I am using Tamiya Arcylic paints I buy at hobby store. You can skip the wrap or paint but make sure you clean the shaft first.
