Again, I need to dig into your experience.

I spent the whole of this years UK summer ( It was a Friday last month) polishing my hull (GRP) as was amazed how the old faded yellow became white again. I went to the boat yesterday and see that it has gone yellow again down near the water line. While it comes off with a bit of the old elbow, I am fed up with the old girl looking off colour.

I am due to repaint the hull this off season (DIY job) and am wondering if there is any product out there that will prevent this.

I am even toying with the idea of changing the colour just so that it will look better.

Any comments out there on a colour/paint type that may better survive the muck and grime of the Solent (Moored in Portsmouth)

Thanks in advance

Wayne

The browny-yellowy stuff on the waterline more or less washes off with dilute oxalic acid, of 'teak brightener' fame. You just need a dedicated sponge head mop. God, what a saddo I am, knowing this.

If you burnt yourself with oxalic it must have been quite strong. You should wear gloves anyway because it is poisonous and the poison can be absorbed through the skin. The chandlery boatwashes which contain it state they have it at (usually) 10% by volume. I'm afraid school chemistry eludes me but someone will tell us how to calculate what it should be adding crystals to water. But burning yourself sounds to this non-expert miles to strong!

I use one tea spoon full in two pints of water ,which i put on with
a large paint brush,This is enough to do the hull of my Sabre 27.
Keep a hose or bucket of clean water nearby to wash off any splashes,
on your person ,Always manage to splash myself ,But quick rinse no problem,
