We own a 60ft narrowboat, with a cruiser stern that we had an immense amount of fun painting last summer. However we only managed to get one Toplac top coat on. I would like to add more coats to give it a depth. Could you help me by telling me how much, and what grade of, sanding I should do before painting. Secondly, what I should do to restore the anti-slip on the gunwales and rear deck?
