I'll be painting the inside of the cabin as well in the next month. I will be using some awlgrip I have left over...moondust I think. With the boat tapped off with no ventilation I won't be spraying. I'll be using the same method as Jason King suggests....lots of flattener and using the roll and tip method. I do plan on priming first which is a must if you have made any repair work, if you don't the paint will look different in that area.
