A clean, well-finished engine not only looks better but performs more efficiently. Restoring surfaces to their original luster and replacing worn parts ensures proper clearances, sealing, and cooling, which are essential for peak performance. Moreover, presenting an engine in its best possible condition reinforces a shop's reputation for quality work. A "like-new" look is a mark of craftsmanship and attention to detail that can attract repeat business and referrals.
Goodson's Last Blast Spray Paint quickly restores bare metal, rebuilt engine parts, and castings to OE condition. However, proper preparation is essential to prevent smudging and ensure the paint properly adheres to the metal.
Follow these steps to achieve a flawless factory finish:
Surface Preparation
- Clean & Degrease: Wash parts or rebuilt components with Goodson's Parts Tumbler Solution | PT-SOL or another heavy-duty automotive cleaner.
- Remove Rust & Scale: Sand, wire-brush or media-blast off any existing corrosion.
- Etch the Metal: Spray or wipe the part with a metal prep solution to neutralize hidden rust and create a textured surface for the paint to grip.
Application
- Mask & Ventilate: Tape off areas not being painted and ensure you are working in a well-ventilated area.
- Shake Vigorously: Shake the aerosol can for at least one minute after you hear the mixing balls rattle.
- Spray Even Coats: Hold the can 8 to 10 inches from the surface and apply in light, overlapping strokes. Avoid laying it on too thick to prevent runs.
Drying & Curing
- Quick-Dry: Last Blast formulas flash off and dry to the touch in just 10 to 15 minutes.
- Full Cure; The paint cures fully in under 24 hours.
- Protect the Nozzle: When finished, invert the can and spray for a few seconds to clear the nozzle.
Optional Finishing Touches
- Clear Coat: For environments exposed to chemicals and heat (such as a transmission housing or steering linkage), topcoat the dried paint with a 2K clear coat for added durability.
