touching up a two part paint

[rebel heart]

I have a painted wooden mast, epoxied and two part painted (sterling). There are some cracks in the paint, small stuff from where (I believe) the wood is flexing a bit. We've moved from a rather temperate region to some super dry conditions.

Anyway...

There are some places where I want to touch up the paint. Can I just 220 the sorrounding area and use Interlux Perfection (my preferred two part paint) following its application guidelines?

Interlux has this for "previously painted surfaces":

Can be applied directly over two-part catalyzed coatings, that are in good condition, by cleaning with Fiberglass Surface Prep YMA601. Sand with 220 grade (grit) paper. Remove sanding residue with Brushing Reducer 2333N.

I think the only problem comes from trying to buff out the surface so everything has the same gloss and blends in. If you don't care about that then all is well. This is one reason the pro's use Acrylic Urethane as it blends in better for touch up. If you tape to a seam or line, no problem.

Sure, but it won't match, and if you 220 prep you must prep and apply to a tape line with no blend. This will leave a hard line. It'll look pretty hideous.

It's probably ~30 up a ~50 foot mast; the only reason I saw it (and can fix it) is to haul my ass back up there. Definitely will be a lame job having to work with paint like that way up high. Especially considering the 5 different steps to "get it right".

I'm just glad there's nothing about primer or sanding anymore than 220.

It will be white on white, three stories up. I'm good with it.

You certain those cracks aren't indicative of a more serious problem? I'd moisture meter and hammer sound to be certain.

I think it's okay. It's a spruce mast that was epoxied and painted, and I think some of the movement on the spar caused the epoxy to crack, and the paint to crack along with it. There hasn't really been any appreciable moisture, but I'll check it regardless.

A couple of years ago I went through the whole mast laid out flat. Can't imagine it got rot with no rain under paint and epoxy. But I'll check regardless.

Better safe than sorry, right? Only takes a few minutes to check her out, if you're already headed up. Good luck! Don't forget to scotch brite up to the tape. I have a neighbor with a bright stick who applies two coats in place each spring, if that makes you feel any better...

I used to have mine varnished and although it's "better" in a lot of ways, I sure don't miss going up and down five stories dripping varnish in the breeze. I bet my neighbors are happy I stopped as well. A lot of wooden boat purists gave me the stink eye when I decided to epoxy and paint.

How many of them are in or going to the tropics?

Yeah not many. The 30-45 degree latitude band definitely seems to be the place to keep your boat bristol finished.

No doubt. Almost done epoxy sealing and painting the vast majority of my brightwork.

I'm letting a lot of my brightwork burn off in the sun and I'm getting about 2-3 dockwalkers a day coming up to me, quite nicely, asking to do my varnish. I just laugh and politely say, "No gracias, varnish es loco y mucho dinero. Tango una familia, no quiero la problema de varnish."

Pigeon Spanish, but it gets the point across.
