I need to paint my rudders. I last used marine paint but this is now expensive-is marine paint any different to a good quality oil based gloss?
 
No mine are made from epoxy laminated 3x18mm marine ply. Just wondered if marine paint is anythging special-apart from the price!

Above the waterline I would say marine paint is tougher and keeps its shine longer.

You can avoid the "marine tax" by using Dulux 10-Year outdoor Gloss. I've had good results having painted my topsides with it three years ago, and a fleet of sailing school dayboats that I supervised the painting of, in 2013, are still looking good.
I should point out that on my own boat, only the topsides were painted with it, I used a hard antifouling for the boot-top, and of course the bottom was coated with eroding AF. The sailing school boats have a fairly high waterline in eroding AF, and while the rudders are painted in the Dulux from top to bottom, they are lifted of their mountings and stored in the cockpits when not in use.

Don’t get it myself - of all the boat expenses, paints suitable for salt water immersion (e.g. Jotun epoxies, vinyl primers and 1/2-pack topcoats) aren’t a major ‘marine tax’ factor for us. And we recently completed a 9 coat osmosis barrier/post-repair coating on our 41’.

The last few threads like this I posted on, it even turned out the Jotun paints were cheaper (per 5l) than the house stuff.

Maybe it’s just me?!

It is not a biggie in itself more a case of straws and camel backs....

I can certainly see this for smaller quantity requirements (1 or 2.5L). But, for me, it’s always worth considering whether a 5L tin might come in handy (they last a year or two in our experience) and work out cheaper in the end. SML primers and topcoats are even more affordable (all <£50 for 5L, inc. 2-pack epoxies and polys, with some 1 component options in the mid-£30s).
