I thought you add wax to the gel coat to make it go hard. I would not be adding THE wAx to the first two coats and then keep it tacky. Then add the flow coat on the last coat so all the layers go hard. Then I would not need to sand between coats?
Sorry, you are right I was having brain fade .... Apply gel coat one after the other, preferably when one has gone tacky then apply the other and there is no reason you can't do the same with the flow coat, that is when the second gel coat has gone tacky. No need to add wax to the flow coat as it already has it added.
