Nasty rash!

   Are there any rivets in that joint? Looks like there's a couple towards the back of the mast in that top picture? if so, I'd be worried that they aren't properly insulated, and you've got some 'orrible galvinic effect going on there.
Whatever the cause, you're going to need to strip back to redo it. be careful doing this, you need to avoid damaging the fibres. If you're stripping back and you do reach the fibres, and the resin still looks like that, then, um, that's a very bad thing.

	Ok you lot, this ain't pretty - I've got a nasty rash around me hounds..... Seeing as there were some pretty insightful and informed comments on the painting a boat thread, has anyone seen this before? The lacquer on the mast is smooth and sound apart from around the spreaders and hounds where it looks 'orrible! Not only is it flaking but it feels as though it has crystals growing in it. Someone told me it was 'carbon mite'- not sure to believe them. Any advice? Is it just that the previous owner used the wrong stuff and it isn't flexible enough around the high load points? Current plan is to strip it all back and re-do with two-pack.
