Before I go to the bother of taking it off the boat and sending it away, does anyone know roughly how much the regalvansing will cost me? I can buy 25 metres of 8mm short link or around £5 a metre.
Galvanising that little bit would cost little if you could put it with someone else's load - 25m is about 35kg, most galvanisers have a minimum order weight of 250kg.
I re-galvanised a 25kg anchor, which cost a putative £6.80, in the W Midlands.
