I'm already a big fan of two part paint. That's what I originally used on my Spindrift over four years ago. It's a daily use tender that carries bikes, kedge anchors, etc, do it gets bashed about a bit. I need the durability of two pack.
Over the years I've picked up tins of whatever was available locally- in Europe I used International Perfection, and in the Caribbean I found a tin of Jotun Hardtop.
Back in the UK I paid about £80 for 2.5l; in Spain it was about €45 for a litre, and the Jotun was about the same price.
The International appears to have been discontinued, and in any case I found that the B component always went bad soon after opening, despite my best efforts.
