One More Fundamental Question
As long as you stay within the recommended times for the product you are using, you do not have to resand between coats. All products vary. For example, the epoxy and basecoat I use have a maximum time of 24 hours. That means I can put on an additional coat (without sanding) anywhere from 15 minutes to 24 hours.
You need to consult the specs for the product you are using.
