Vintage Car Parts Restoration

Engine-bay parts that look like the build deserves.

Tumble finishing for the small metal parts on a restoration: valve covers, carburetor bodies, brackets and pulleys, small covers, motorcycle heads, hardware and fasteners. Rust, old paint, and oxidation come off; a clean uniform satin or burnished surface goes on. Phoenix Valley only — drop-off by appointment or scheduled pickup for shops.

Driver-quality finishes
Clean satin, brushed, and burnished — right for engine bays and hardware.
From $75 / lot
Per-lot pricing plus $95/hr for disassembly and heavy prep.
In-week turnaround
Most lots finish the week they arrive.
Up to ~30in long
Parts up to about 30in x 12in x 13in run whole, no cutting.
What fits, what doesn't

Small parts, not sheet metal.

The tumbler interior is 33in × 14.5in × 16in, so the practical max part is about 30in long × 12in wide × 13in tall. Valve covers, carbs, brackets, pulleys, small covers, heads, and hardware all work. Bumpers, wheels, grilles, and body panels do not — and we don't chrome plate or mirror buff. For those, I'll name a local shop that does.

Anything metal that fits the tumbler: valve covers, carburetor bodies, intake and timing covers, brackets, pulleys, small differential covers, motorcycle cylinder heads, suspension hardware, fasteners, trim clips, and vintage tooling. Parts up to about 30 inches long run whole.
No. Those exceed the tumbler's width and depth, and we don't plate or buff. Bumpers, wheels, grilles, and body panels need a plating or mirror-buff shop — I'll point you to a local one.
No. This is vibratory tumble finishing: clean, uniform satin, brushed, or burnished surfaces. It's the right process for engine-bay parts, hardware, and driver-quality restorations, not for mirror show chrome.
Media is chosen and cycle time capped to protect those features, and critical faces get masked or plugged when needed. Tell me which surfaces are critical when you send photos and it gets handled in the setup.
Per-lot pricing with a $75 minimum, plus $95 per hour for hands-on prep like disassembly or heavy degreasing. Send 3 to 5 photos with rough dimensions and the lot gets quoted, usually within a business day.
Yes, as long as the individual pieces fit. Bagging fasteners and small hardware by assembly keeps them organized and keeps prep labor down.
