Painting or restoring an engine to bring it back to its former glory is now a common and increasingly important practice for motorcycle and car enthusiasts.
This topic includes vintage cars and motorcycles, but also modern vehicles, considering that engines—especially in two-wheel vehicles—are an integral part of a vehicle's aesthetics. They can completely transform the look and design of these works of art.
To start approaching this field, we will divide engine painting into various phases so that it becomes clearer how to choose the right paints and how to proceed to achieve a great result worthy of a professional.
PHASE 1: Assessing the Engine's Condition
When looking at an engine, observe some specific aspects.
The first is whether the engine is already painted or not, and if the paint is holding up. Is it flaking off, are there bubbles, is there rust, or is the engine just aged but with paint or metal in good condition—old but still solid?
To be certain, degrease the engine by taking it to a standard car wash, and then carefully inspect all areas of the engine.
PHASE 2: Identifying the Issues
Identifying the problems helps determine the right products to use and which techniques to apply to restore everything in the best way possible.
You may find rust spots, or you might notice blistered paint with areas that have flaked off.
PHASE 3: Resolving Issues and Preparing the Surface for Painting
Any issue must be addressed in one of two ways:
-
Manual Sanding:
You can sand the entire engine or only the affected areas using abrasive paper of varying grit. Alternatively, you can use a grinder with abrasive discs, though this requires skill and familiarity with the equipment. -
Professional Sandblasting:
A more professional alternative is to disassemble the components or the entire engine and have it sandblasted. This allows for a thorough cleaning and, simultaneously, application of an epoxy powder primer for maximum adhesion and protection. -
Common Method:
A third method is to sandblast or manually sand the pieces, always wearing latex gloves (we’ll explain why later), and then immediately apply high-temperature engine primer from Kustom Service. This primer is available in a 1K spray version or a professional 2K version for use with an automotive spray gun.
PHASE 4: Applying the Primer
Applying the primer is quick and easy. It takes just a few minutes, whether you use the spray version or the liquid 2K version.
Once applied, the engine can remain in this condition for up to a year, as the primer protects it from oxidation.
However, the best approach is to paint the engine within an hour using Kustom Service engine paint. This way, without additional sanding, the two layers of paint will bond into one and become much more durable.
PHASE 5: Waiting
For the best possible result, allow the paint to cure:
- 7 days in winter, or
- 2 days in summer.
This allows the paint to set and harden, making your engine resistant to gasoline and other agents.
At this point, you have a complete guide to act based on precise instructions to assess your engine's condition.
