You don't want it on yer galv trailer either!
Oxalic acid itself can be bought on ebay by the kilo in powdered form. As a solution in water it can simply be sponged onto GRP and hosed off - it works well like that. It can be mixed with wallpaper paste for application to stainless steel and to spot apply to more stubborn rust stains on GRP. Obviously the gel has to be physically cleaned off, not just hosed down. I suspect that it is the active ingredient in Y10. A kilo of Oxalic acid costs about £10 and will easily do a couple of 6m ribs, hull and supers.
