Sorry I was responding to Jim's point on GRP. As far as I know rotomoulded doesn't work with any kind of coating. Only mechanical fastening.

How well does epoxy stick to roto moulded plastic?

The simple solution to that is to paint an epoxy barrier coat first, something like Gelshield 200. Alternatively you could even coppercoat, but suspect that lightweight dinghies (speaking relatively to yachts) are the most suited.

Well GRP has its own problems. Materials vary, and if the resins in a GRP boat haven't been chosen to be permanently immersed... I think your first port of call should be the paint manufacturers to see what they recommend.

Thanks really useful info. If roto moulds can't easily be anti fouled then that's them all off our club buying list and I'll have to look Wayfarers and Comet Trios, good 'ol grp:)

I came across a recommendation for plastic car bumper primer as a base for antifouling on a rotomoulded hull. Worth checking out, perhaps!

I strongly suspect you'd have trouble getting antifouling to stick to a rotomould boat, but the best people to ask are probably the antifouling manufacturers.
