Introduction
This article summarizes the conditions and repair steps as presented. The discussion focused on restoring the trim on a Seth Thomas Adamantine clock after the owner discovered that the brass‑colored pieces had turned copper‑colored and did not respond to brass polish.
Identifying the Original Trim Finish
Copper‑colored appearance
The trim pieces appeared coppery rather than brass, even after polishing attempts.
Factory‑applied paint
Some Seth Thomas Adamantine clocks used painted trim rather than bare brass, especially on heavier components.
Mixed materials
Heavier trim pieces such as feet and column bases were made from non‑magnetic, charcoal‑colored metal and painted at the factory.
Brass components also painted
Lighter pieces such as lion heads and rear feet were brass but originally painted copper to match the rest of the trim.
Testing for paint
Lacquer thinner can be used to determine whether the copper color is paint rather than tarnish.
Why Brass Polish Doesn’t Work
Painted surfaces
Brass polish only makes the copper paint shiny; it cannot restore a brass color if the surface is painted.
Not true tarnish
The copper tone is not oxidation but the original or aged paint layer.
Factory aesthetic choices
Some Seth Thomas models were intentionally finished with copper‑colored trim to complement the Adamantine case.
Durability of coating
The paint resembles a powder‑coated finish and does not come off easily.
Preservation concerns
Removing paint may alter the clock’s original appearance and reduce authenticity.
Refinishing Options
Using Rub‑N‑Buff
Rub‑N‑Buff is a popular choice for recoloring trim. It applies easily and produces a metallic finish.
Surface preparation
Loose or scaly areas can be brushed with a stiff brass brush before applying Rub‑N‑Buff.
Application tools
Short‑bristle brushes from discount stores work well for applying the product.
Going over existing finish
Rub‑N‑Buff can be applied directly over old paint without stripping.
Sealing the finish
A coat of gloss lacquer protects the new color and enhances durability.
Alternative Restoration Approaches
Removing paint
Lacquer thinner can remove paint from brass pieces if a bare‑metal look is desired.
Polishing brass
0000 steel wool can polish brass or bronze components once paint is removed.
Preserving original patina
Some restorers prefer to keep the original copper‑painted appearance for authenticity.
Cleaning spelter components
Heavier trim pieces made of spelter should be handled carefully due to their fragility.
Gilding incised details
Gold paste or gilding wax can restore faded incised decorations on the clock face.
Final Results and Examples
Autumn gold finish
Rub‑N‑Buff in autumn gold was used successfully to match the original trim color.
Repainting gold incising
Gold incised lines were refreshed by hand to restore clarity and contrast.
Matching factory appearance
The refinished trim closely resembled the original copper‑gold tone.
Community examples
Other owners shared photos of similar clocks with the same copper‑colored trim.
Preservation vs. restoration
Both approaches are valid depending on whether authenticity or appearance is the priority.
FAQs
Why does my brass look copper?
It is likely painted copper from the factory, not tarnished brass.
Can I restore the brass color?
Only if the paint is removed; otherwise recoloring products like Rub‑N‑Buff are used.
Is Rub‑N‑Buff durable?
Yes, especially when sealed with lacquer.
Should I strip the paint?
Only if you prefer a bare‑brass look; original paint may be historically correct.
Are some trim pieces spelter?
Yes, heavier components may be spelter and should not be aggressively polished.
