There was an old tech note on filling the grooves with minwax, a light color that would match the holly in the sole.  We did that in 1998.  Still working.

I filled my grooves with leftover black Dow 795 from doing the fixed portlights.

Catalina uses Target Coatings waterbased sealer for the interior teak.  I know because I've called Target Coatings and they've sent me a quart of the waterbased product that Catalina gets from them.  There are a few waterbased products and I can't remember which one.  If you call them, they can tell you which one to order.  It's about $25 per quart, including the shipping.  Very easy to use.

I spoke to Warren at Catalina last May and he essentially said this too. If you have a late model MkII with the lighter wood finishes, it is very important NEVER to use an oil stain (like tung) or any oil-based varnish. Once you do that, the wood will be permanently darkened yielding a poor match. He said that the waterbased Minwax Polycrylic should get a similar finish also, although the Target products are waterbased polyester (not acrylic), so your best match will be achieved with the Target products that CatalinaDirect sells. They have a very thorough writeup the history of Catalina's finishing techniques here:

Thanks Breakin Away.  There’s some really good info via the Catalina Direct link you posted.  Good to know what Catalina used historically for wood finishing. I’ve ordered some Target semi-gloss to spruce up companionway stairs.

GUYs : Again - what ever you do to your steps, put some water on them and test so they are NOT slippery.

I know of a 1st Mate that took a "header" down those wet steps hitting the buildup around the galley sink.  It wasn't pretty!!
The steps are not a piece of fine furniture, but should be safe and functional!!

Totally agree.  Cosmetics are cosmetic, but non-skid strips are safe.

I have to refinish my bulkhead panel at the front of the the V-berth (long story - a small leak a year ago - since fixed - caused some water/tannin staining). In addition, my stairs are due for refinishing at some point.

I occurred to me that the bulkhead could be a perfect opportunity to experiment. I much prefer to use a mass market material that could be easily purchased at a local store. The key features of the Target Coatings finish for MkII boats is 1) aqueous material which does not darken the wood like oil based materials and 2) amber finish caused by alkyd content, which can be closely matched by polyurethane. Just about any semigloss aqueous alkyd or polyurethane material should match well, and I'm willing to experiment on my bulkhead because it's far enough out of the way that an imperfect match won't make much difference. I've always had good luck with Minwax products in non-marine and even some marine applications, and they're so huge they'll never go away and their product line is pretty stable so they aren't constantly changing it. Also, the stairs would benefit from a floor-grade formulation for long-term durability. So I'm thinking of getting this:

https://www.minwax.com/wood-products/hardwood-floors/minwax-ultra-fastdrying-polyurethane-for-floors

Floor paints can be pretty bad about sag resistance (since floors are horizontal), so it may take some care in painting the vertical surfaces of the stairs. But the bulkhead is out of the boat, so I can make it horizontal. The biggest problem I'm having is I can only find this in gallon quantities (since floors are generally a large area).

Another option, which isn't floor grade, would be this, which is available in 8, 32, and 128 oz sizes:

https://www.minwax.com/wood-products/clear-protective-finishes/interior/minwax-water-based-oilmodified-polyurethane

Or maybe I'll just stick to the Target Coatings stuff, but I'm just not sure it's necessary because a brand new finish is not going to match anyway even if you use the same manufacturer. The alkyd or polyurethane always gets yellower over time.

BA,

Nice presentation and links.  It could end up being a great tech note or wiki article for Mark II skippers.  Many have asked the proverbial "What finish did the factory use?" question.

Have you considered using the forward side of the bulkhead for a practice range?  Or is that side OK with no H2O damage?

BA

I use Minwax Helmsman, which comes on various sheens.  I think the attached is semigloss (2 coats.)
The cubby fronts are varnish over new teak.

Thanks, Stu. I'll wait until I've actually done something before writing it up. lol

The forward side is in great shape, but also totally unsanded, and would take a lot of effort to make it into a meaningful test. I will probably throw a few coats to seal it, but it will be "hidden quality." I'm going to have my hands full trying to strip off the finish on the exposed side, so I need to focus my energy on that.

I used that exact same stuff (Minwax Helmsman Semigloss Polyurethane) on my badly grayed hatch boards, and it looks GREAT, mainly because the oxalic acid treatment I used to remove the gray left the wood extremely light, so the oil based finish restored a rich, medium color. It's held up well for 2 seasons, and I just did another single coat to refresh. Since I would prefer to use up my existing materials than buy new, I tried a test patch with the Helmsman on this bulkhead, and it was way too dark. I immediately doused it with acetone and stripped it off before it cured. The problem is that Catalina switched to waterbased varnishes with the MkII boats (due to CARB regulations), which is why the interior wood on all the MkII boats is a much lighter color. MkII owners need to use a similar waterbased varnish to get a similar finish (either polyester/alkyd, polyurethane, or maybe acrylic). The acrylic may not be yellow enough, so I'm not going to try that.

Very personal decision but I take a more holistic approach to wood finish color matching. Each piece of wood has its own unique beauty, ages differently,  is a natural “product”, and every piece doesn’t have to match its neighbor. As long as it has a nice well applied finish, “a close enough color match” works for me. I have a MkI with oiled furniture/interior, matte varnished sole, and high gloss oil based varnished exterior.
