I have used it. It is good but I highly recommend the primer first as I have done both ways. The primer will help hide stress cracks, without primer does not. I still recommend body filler for any larger cracks though. 1 qt will give you several coats for hull bottom. I have only painted white so I am not familiar with the colors application.
How close would 2 coats of red come to doing the job of one coat primer/one coat red ??????
I realize this question may just make me appear ignorant, but I'm considering this option as well. Or, I may change color of this orange hull to white as that's what I already have on hand.
