Product Questions

Hi thereWould you be able to tell me if this is the right primer I need for my GRP boat? I’ll be using it mainly on the keel and a little bit around the boat that’s slightly above the water line, I have got a old tin of interspeed extra strong antifouling and I need to purchase another tin from you which I believe is ultra 300 is this the right primer. Also I’m after yours brass drain plug just hope it fits as it’s a 40yr old boat and it seems to measure 19mm the actual plug as that’s all I need but understand it the whole thing. Also after some good cup holders and small dumpy fenders 9” long. Look forward to hearing from you.Mike

Primocon is the perfect underwater primer to go under antifoul such as International Ultra 300. It is happy being applied to both metal keels and GRP. Our brass drain bungs (890379 & 890380 both use a 1/2" BSP thread, which have an internal diameter of around 19mm, so could work.
