Outlaw Kustoms Teaches us the Proper Way to Paint an Engine

By “Rotten” Rodney Bauman – Images by the Author & Daryl Sment

“If there’s anything an old painter can do around here, I’ll do it.” That was pretty much my pitch, and it paid off with a much-needed short-term job at Outlaw Kustoms in Albuquerque, New Mexico.

Backing up briefly, just to paint the picture, it was a wife’s-side family reunion that necessitated a road trip to Albuquerque. No offense intended toward New Mexicans, but I don’t much care for Albuquerque, its big balloon festival, or its big lavender festival for that matter. Rather than blather in dull detail, let me just say that I don’t get much out of family-planned tourist activities—at all.

As I’m arriving late to my first day at my new job, head fabricator (and more) Daryl Sment is already deep into this engine’s paint prep.

Knowing well ahead of time that I’d likely need an escape, I did a little Web search for hot rod shops in the area. When I came upon OutlawKustomsInc.com a mental note was taken. Upon arrival to Albuquerque, I took a chance, called the shop, and received an invitation to stop by and have a look around.

I went there the very next day, met proprietor Angelo Vigil, his wife (and business partner) Crystal, and the multi-talented head fabricator (and more), Daryl Sment. They didn’t seem to mind me hanging around, but like I told ’em: “I’m not used to doing nothing!” Sure, I’m always sniffing around for a tech story, but I’ll put my painterly paws on a project, too.

To help me have a purpose in Albuquerque, Angelo and Sment kindly thought it over. Undercover, on a stand near the wall sat a freshly rebuilt 6.0L LS still in need of a fine finish. I could do that. “It’s right up my alley” I told ’em, but I wasn’t yet fully aware of Outlaw Kustoms’ sky-high standards.

Righty-tighty, lefty-loosy, but I didn’t audibly say that to Sment. Anyway, at this point with the stippling all done, it’s an OK time to pull this valley cover.

As I discovered on the fly, Outlaw Kustoms is responsible for some truly noteworthy classic truck builds. Most recently, 2024 Builder’s Choice, presented by Hot Rods by Dean, and 2025 Truck of the Year Late Finalist, presented by Dakota Digital. Never mind I’m an experienced painter. Never mind I’ll only be painting an engine. Instinct now suggests that I’ll need to rise to this occasion.   

Through the years I’ve painted many engines, but this’ll be my first LS. Initial inspection reveals some rather difficult shapes. The engine block’s casting has ribs, and other crooks and nannies that’ll call for some pretty sharp shooting. Casting numbers were already ground away before I’d arrived, but there’ll be more work required to achieve a uniform texture for block and heads. At Outlaw Kustoms, we call that “stippling.”

If masking isn’t rocket surgery, let’s see a rocket surgeon do this. While I’m fumbling with a single-edge razor blade, Sment is dead-on accurate with an X-Acto knife.

Since I didn’t pack my own spray equipment, I’ll be working with what’s here. As it turns out, Outlaw Kustoms uses Iwata-brand spray guns, so this’ll be my opportunity to assess what’s widely considered the best. Back at our own shop, I’ll stick with my trusty mid-’90s ’guns, but if I thought I’d stay in the game much longer I’d call Summit and step up for Iwata-brand replacements.

When we’re eventually satisfied that our subject engine is surgically clean, abraded, and properly masked, we’ll apply epoxy primer to start. Afterward we’ll clearly see any minor surface imperfections and correct as necessary.

Basecoat tacked off, we’re confident that no fuzzy dry overspray remains. Taking the next step, Sment applies acrylic urethane clear.

Providing things go according to plan, next-day action will be standard procedure. It’ll be basecoat and urethane clear, but materials in stock are foreign to me. It’s not what we’d use in Montana. It might not be what you’d use where you are, so for the how-to portion of our story let’s focus on technique, not so much on brands.

In the past there’ve been times when it’s done me good to work in other shops with other craftspersons. Lately, I’m a dinosaur, still doing things as I have for eons. If I’m not real careful here, I just might learn something new. If I have my own way, you just might gain from this experience, too.

Freshly rebuilt, this engine’s exterior might be a little oily. Here the needle scaler isn’t used so much for cleanup, it’s used to create that uniform stippled effect.

The valve covers will remain in place for the time being. They’re only there for masking purposes. They won’t be used for anything else.

And speaking of masking, we’ll have a good deal of that to do. First things first, let’s make sure that surfaces to be masked are surgically clean and dry.

In situations such as this, cheap masking tape would likely let us down. The yellow tape used here is leading-brand (3M). Back at our own shop, we get ours through Summit.

In conjunction with waterborne and solvent borne grease and wax removers, we’ll be using other Summit staples to prep this engine for paint.

For example, leading-brand (3M) scuff pads and clean disposable toweling come into play here. While we’re at it, let’s have a close-up look at the block’s crooks and nannies.

At this point we’ve got a pretty full day’s worth of paint prep done. Now in the booth, an acetone bath is our final prep step. In the morning, the sharp shooting shall begin.

Before we exit the booth tonight, this invention deserves a mention. It’s like an exhaust wall that captures overspray within standard-size paint booth exhaust filters.

Here on the B-side, what makes it tick? How about 12 individual electric fans? How many to run is the painter’s call. There’s also a waterfall feature to arrest aroma.

As I’m arriving late for my second day, in-house painter Josh Ramacciotti is already mixing epoxy primer. This brand flows best in mild temperatures, so it’s a morning job.

Now here’s an old painter’s trick that I’d actually forgotten about. V-shape some tape and you’ll gain a handy pour spout for better control and far less mess.

If you hear a sigh of relief, that’s me. Ramacciotti will do today’s shooting. Since I don’t work so well on my worn-out knees, I’ll just stand around and shoot photos.

Logically choosing to begin with the block’s tougher crooks and nannies, Ramacciotti has his Iwata gun’s material knob dialed down and he’s shooting at fairly low pressure.

Up top, he opens the material knob as necessary for a uniform wet coat. The engine will receive two coats of epoxy primer, then we’ll scrutinize our work.

Did anybody bring a magnifying glass? I’d need one, but Angelo Vigil won’t. If there’s an imperfection in need of correction, the boss will find it.

And sure enough, we have a few tiny pinholes. Ordinarily those are easily fixed, but since we’ve exceeded our chemical bond window, the epoxy coating must be abraded.

A few days later, the shooting resumes as a tag team effort. Here Daryl Sment applies the basecoat color. By this time heads have been removed for an ARP bolt upgrade.

Older painters may recall those tacky orange tack rags we sometimes had to use. Today we have less-tacky basecoat tack rags. Used properly, these won’t leave a tacky mess behind.

Things to do in Albuquerque: Big balloon festival, big lavender festival, shopping in Old Town, hiking up a hill to see a lizard, and so on. Thank you, Outlaw Kustoms!
