Ready to paint my HC 16 first build. I know nothing about paints, primers and finishes in general. I note that your last post on the topic was years ago. What's the latest and what do you recommend?

It really depends on what you want to get out of the paint. The System Three LPUs are "okay" smaller selection of colors, and I've seen a few minor issues with them. If you want to go for what the pros use I'd suggest Awlgrip. EMC is also good, and repairable (it's comparable to the Awlcraft line from Awlgrip)

I would not use the System 3 LPU's. Cracker Larry used it on the inside of No Excuse and I am having to repaint it. Go with Awl Grip or EMC for a longer lasting finish. For primer nothing beats the Silvertip Epoxy High Build Yacht Primer sold here.

>8 Years is still not bad for a paint job. As they say, you get what you pay for. The awlgrip probably lasts a good 20 or so if well kept.

With apologies, I'm going to repeat what I've said elsewhere and put in a word for us paupers. All the LPU's are very expensive so if you, like me, anticipate your boat not being kept in a velvet cradle in a humidity controlled shelter, you may, like me, wish consider a less expensive option. Of course, you've put in a lot of effort and you want the paint to last and be great looking, and may consider cheaper paint a false economy. But after a few run-ins with pilings, dock rash, and oyster shells and rocks on the beach, even the most expensive paint will be driven to submission.
I used Interlux Brightside. It took several coats for me to come up with the right application process but now I can do it very quickly with ease. It really looks amazing if you do it right. The Brightside I put on the shear stripe of my big boat looked good for ten years.

Another paint related question - can I overlap topside paint over epoxy+graphite (sanded first) or do I need to prime the epoxy+graphite first?

No need to prime as long as you rough it up with sanding first.

Question: Why are you putting paint on top of the graphite? It doesn't need further UV protection and the paint won't be as hard as the graphite/epoxy.

I think he's just working out the overlap procedure. :)

I overlapped the lpu topsides with bottom paint. Sand prep the area of the overlap first and prep as required. Then i sand prepped both (cured) carefully, and painted the bootstripe over the meeting of the dissimilar paints. Topsides and bootstripe are still stuck, but the s3 lpu on the deck and 'sun surfaces' did not handle southern sun well. Cracked and flaked. Just started to need some care on the topsides. If I paint again anytime soon, it may be emc, not s3 again. But the s3 primer is nice. If you try to find out if a finish system is compatible with it, don't expect much official help from a company. They want to sell their own primer for their own finish system. I understand that. But I sure do like how easy the s3 primer is to use and shoot. :)

Rather than taping off just the underside when applying the graphite+epoxy, I went ahead and covered the entire outside of the hull (SK14). The thought was that having the graphite under the paint on the sides wouldn't be a bad thing.
