Hi There

I am in the process of wet sanding the undercoat on my hulls, as long as the hulls are built reasonably fair (checking with batten along hull sides while fitting of the frames) you'll be able to do it with 4 litres of epoxy primer (Dulux Luxepoxy White) and you'll easily do it with 4 litres of top coat (I'm using Dulux Luxethane 2 Pac).

I spent probably 4 hours wet sanding one hull yesterday and I'm not finished yet, due to my sub standard spray painting skills, or more lack of knowledge regarding spray painting.

Regards
