Hull White contains an organic mixture of polymer gelling agents, oxalic acid, surfactant and glycol
based solvent mixtures for the cleaning of fibreglass hulls.
Hull white can be used on any fibreglass surface which has become discoloured through age and
weathering.
It is effective at removing the brown/yellow staining on the waterlines of boats.
As it is a gel, it stays where you apply it, even on vertical surfaces, meaning it can stay in contact
with the surface for a longer period of time.
