Most builders track every dollar that goes into a build. The motor, the bags, the wheels, the paint. What gets tracked less honestly is what comes after. Keeping a custom truck looking the way it did the day it rolled out of the booth is its own line item, and it adds up faster than most owners admit.

No published survey tracks exactly what custom truck owners spend per year on finish maintenance. Anyone quoting a precise national figure is guessing. What does exist is industry context, retail pricing, and regional climate data. Put together, it tells a clear story.

The Market Reality

U.S. consumers spent roughly $52.65 billion on vehicle accessories and modifications in 2024, according to the most recent SEMA Market Report. Pickups account for about 32 percent of that spend, more than any other vehicle category. Appearance and accessory products (paint care, coatings, polishing, wheel and trim) make up one of the largest slices of the total.

That number does not tell you what one truck owner spends. It does tell you that the maintenance economy around custom trucks is real, and that the average vehicle on the road is now around eight years old. More older trucks are getting kept and cared for instead of traded in, which is exactly the audience this matters to.

A detailer at Panda Hub who has been providing car detailing services in Philadelphia for several years, told us: “Two trucks can have the same paint, the same coating, and the same show schedule, and end the year a thousand dollars apart on maintenance. The variable nobody talks about is the owner.”

What the Money Actually Covers

Annual finish maintenance on a custom truck breaks into three buckets.

First is consumables: wash media, iron removers, drying towels, ceramic top-up sprays, polish, pads, interior cleaners. This is where DIY builders save the most. A reasonable home detailing setup runs anywhere from a couple hundred dollars into four figures depending on how deep the cabinet goes.

Second is professional services. Paint correction, ceramic coating application, ceramic coating maintenance washes, pre-show details. A full pro correction with a coating refresh typically runs in the four-figure range and gets done every 18 to 24 months on a serious build. Maintenance details between coatings are cheaper but add up over a show season.

Third is everything around the truck itself: covers, indoor storage, climate control, trailers. Builders running a five-event circuit usually spend more here than they planned for.

Conclusion

The right number to budget is not a national average. It is what your specific truck, in your specific climate, with your specific show schedule, actually requires. A daily-driven cruiser that sees two local shows a year is not in the same bracket as a regionally toured restomod logging 4,000 miles a season.

The builders whose trucks hold their finish the longest are the ones who treat maintenance the same way they treat a build sheet: planned, budgeted, and done before there is something to fix.
