I Learned the Hard Way: Why 'We Do Everything' Is a Red Flag in Wood Finishing

When "We Can Do That" Isn't a Good Answer

I've been handling custom finishing orders for about eight years now. I'd like to say I started out smart, but that wouldn't be true. In 2019, I made a mistake that cost me $890 in materials and a week of delays, and it all started because a vendor told me they could do anything.

That's the thing about the finishing industry—especially when you're dealing with heritage products like McCloskey's Man-O-War spar varnish. It's a very specific beast. And not everyone who says they can handle it, actually can.

The Check-List I Now Use for Any Specialty Finishing Order

After that 2019 disaster (we'll get to it), I put together a simple checklist. I've used it on roughly 80 orders since, and it's caught problems on at least 15. Here are the steps, in the order I run through them.

Step 1: Verify the Supplier's Track Record With This Specific Product

This feels obvious, but it's the one people skip. I don't mean "Do they sell spar varnish?" I mean, "Have they successfully handled Man-O-War—the McCloskey formula—on a project like mine?"

For the job that went wrong, I was sourcing a custom batch of Man-O-War for a client's outdoor furniture. The supplier I called said, "Oh yeah, we do varnish all the time." I didn't dig deeper. (Note to self: never accept that answer.)

What I do now: I ask for a specific reference. "Can you show me a batch record for McCloskey Man-O-War?" If they can't, they haven't done it.

Step 2: Confirm They Understand the Curing Requirements

McCloskey's Man-O-War varnish isn't your standard polyurethane. It has a specific curing window, temperature sensitivity, and it hates humidity. I learned this the hard way when my 2019 order arrived looking like orange peel. The supplier had rushed the curing process—probably to hit my deadline—and the result was trash. $890 worth, straight in the bin.

Checklist item: Ask the supplier to walk you through their curing protocol for the specific product. If they can't, walk away.

Step 3: Get the Batch Number and Trace It to the Source

This is a step most people in my position (especially newbies) overlook. I now request the batch number for the McCloskey product before it ships. This lets me verify it's genuine—McCloskey has a fairly tight distribution network, and counterfeit or mishandled stock does appear. (Circa 2021, I caught a batch that had been stored improperly—the viscosity was all wrong.)

Why it matters: A batch number gives you a paper trail. If there's an issue, you can trace it back to the actual manufacturing run, not just the supplier's word.

Step 4: Ask About Their Experience With Your Application Method

Are you brushing? Spraying? Wiping? Each method requires slightly different viscosity and application technique for Man-O-War. A supplier who only knows spraying might give you a formulation that's too thick for brushing.

I once had a supplier (different from the 2019 one) who said they could do it all. Turned out their experience was almost entirely with industrial spray systems. My client was hand-brushing. The result was a nightmare of streaks and bubbles. The vendor who said, "this isn't our strength—here's who does it better" earned my trust for everything else.

Step 5: Get a Written Guarantee on the Color and Sheen Match

Industry standard color tolerance is Delta E < 2 for brand-critical colors. Delta E of 2-4 is noticeable to trained observers; above 4 is visible to most people. (Reference: Pantone Color Matching System guidelines.)

For McCloskey's products, the sheen is especially tricky. The Man-O-War line has specific gloss levels, and they can drift between batches if the supplier isn't careful. I now request a written guarantee that the final product will match a provided sample within Delta E < 2. This isn't standard for most finishing orders, which is why you have to ask for it specifically.

What I Learned About Boundaries

Here's the uncomfortable truth I've had to accept: I'm not great at everything. And more importantly, the best suppliers I work with aren't afraid to admit their own limits.

The vendor who lost my 2019 order? They genuinely wanted to help. They said yes because they didn't want to turn away business. But they didn't have the specific expertise for McCloskey's Man-O-War, and they didn't tell me. The result was bad for both of us.

I'd rather work with a specialist who knows their limits than a generalist who overpromises. That's not a criticism of generalists—it's just reality. No single operation can be world-class at everything. The ones who try end up mediocre at everything.

My experience is based on about 200 mid-range to premium finishing orders. If you're working with luxury or ultra-budget segments, your experience might differ significantly. And I've only worked with domestic suppliers so far—I can't speak to how these principles apply to international sourcing.

There is something satisfying about a perfectly executed specialty order, though. After all the vetting, the checking, the curing wait—seeing that McCloskey varnish go on smoothly, cure correctly, and last for years outdoors, that's the payoff. It's worth the extra steps.
