Hi Doug,
Not much to add to Nick’s post. I used “ivory” white in A1 as I find pure brilliant white just a tad too much. It was/is a marine paint but doesn’t appear to perform any better than Dulux which I used to good effect on previous boats.
Goes without saying, but start at the top and work down! Also would recommend wearing a hat of some sort!
Good luck – seems like you’re on the home straight.
Mike
