I’m Louis Jasso—a third-generation wood coatings specialist with a background in industrial wood coatings and a passion for custom trucks. You might’ve seen my work on the hit TV show Texas Metal on MotorTrend.
After years of going to shows around the country, one thing still drives me nuts: seeing killer trucks with high-end everything… and a wood bed finished with hardware store spar varnish.
The truth is, most builders are still using outdated, brittle coatings on one of the most visually important features of their truck. Let’s change that. If you want your wood bed to look as dialed and durable as the rest of your build, these five tips will get you there.
Tip #1 – Ditch Spar Varnish Once and For All
Spar varnish might’ve been the go-to twenty years ago, but it’s no match for today’s expectations. It yellows fast, cracks under stress, and once it fails—it delaminates so badly that repair means a full strip-down. That’s not protection. That’s a liability.
If you're using varnish on a show-worthy bed, you're doing your truck a disservice. You need a modern industrial coating that’s built for UV exposure, temperature shifts, road grime, and daily wear.
This is a great example of a failing spar finish
Tip #2 The Best Clear Coat For Wood Truck Beds
Most clear coats on store shelves are meant for decks, fences, or furniture—not custom truck beds. KustomKlear is different. It was developed from industrial wood product chemistry, not some repackaged home improvement formula.
This water-based coating holds up under extreme conditions and delivers that slick, glassy look without yellowing, flaking, or clouding up. And the best part? When it eventually wears, it does so from the top down—so refinishing it is quick and painless.
“You wouldn't use house paint on your truck body. So why treat your wood bed like an afterthought?” – Louis Jasso
Tip #3 – Make Application Garage-Friendly
One of the reasons pros love KustomKlear is how easy it is to apply. You don’t need a paint booth or expensive gear. You can brush, roll, or spray it—and since it’s water-based, cleanup is a breeze. The dry time is fast, the odor is low, and the end result looks like it came out of a high end furniture factory.
I’ve seen garage guys lay this stuff down better than some professional shops I’ve seen on TV.
Tip #4 – Think About the Long Game
Everyone wants that perfect look for show day—but what about six months later? Or a year? KustomKlear doesn’t just look amazing—it lasts. It’s flexible, won’t chip, and keeps your wood grain protected without locking in moisture. Plus, when it’s time to touch up, you don’t need to start over. Just scuff, recoat, and you’re back in business.
That’s why more builders are making the switch.
Tip #5 – Don’t Overlook the Wood: Finish Strong
Lastly, remember this: your truck bed is often the centerpiece of your build. It’s where we keep the ice chest/beer, your favorite chair, and hopefully the best of show trophy when you leave the show. The right clear coat makes your bed a showstopper—not a weak point.
Stop reaching for quick fixes. Use a product made for performance, longevity, and beauty.
Final Thoughts
If you’re building a classic or custom truck with a wood bed, you owe it to yourself—and your build—to use the best finish possible. KustomKlear isn’t just a product, it’s the new industry standard!
