Not to bad considering how much salt it has seen.I'm guessing your starting to see rust lines at the welds? You will get that.There are products avail.Galvacon is a good one.It is a galvanize spray paint,just make sure the area is dry(water not weeping through weld)a bit of a clean with a wire hand brush to remove rust stains will help.I buy it from Acklands,but there might be a comparable product at your local Crappy tire.One note, it is kind of a matt grey colour and does not look exactly the same as galvanizing.It is not as tough as the real thing but for seasonal touch ups it's all right.Good luck,Lots of masking with the boat on!!!
