Rust-oleum 249340 High Heat Auto Spray Primer 12 Oz

Product Description

The RUST-OLEUM 249340 is a high-heat aerosol spray primer formulated for automotive engines and bare metal surfaces that reach intermittent temperatures up to 2,000 degrees F (1,093 degrees C). It bonds directly to bare metal to create a smooth base coat that promotes adhesion of topcoat finishes. The formula includes corrosion inhibitors to prevent rust formation on treated surfaces. Packaged in a 12 oz aerosol can, it is applied by spray and is suited for use by automotive technicians, restoration shops, and trade professionals working on high-temperature metal components.

This primer is intended for use on automotive engines, exhaust components, and other bare metal surfaces subject to high intermittent heat cycles. It is appropriate for both professional shop environments and field service applications where bare metal must be primed before a high-heat topcoat is applied. The spray format allows even application on irregular engine surfaces and tight spaces.

Installation Notes

Surface preparation is critical before application — remove all grease, oil, rust, and loose scale from bare metal prior to priming. Allow the engine or component to cool completely before applying. Follow all applicable safety guidelines for aerosol use including adequate ventilation. Allow primer to fully cure before applying a topcoat or returning the component to service.
