At the moment just started on the deck of my boat it's got a sort of grey paint (no anti slip involved) undercoat on it at the moment
This is about 30 mins of work but the deck is quite lumpy so some bits remove quicker than others.
Do just remove it all or just the loose easy bits then key up rest and flowcoat over.
Or is it best to just completely remove all grey paint down to the flowcoat.
I want to flowcoat orange over the top of this as I have lots of holes to fill in deck and I want a nice thick seal over the top of them.
Also I'm going at it at the moment with a random orbit sander with 60 grit is this the best tool for the job or is it best to use a grinder with flap disc.
