TRUEGARD 304 Rust Preventative - 55 Gallon Drum

TRUEGARD 304 can be applied by spray, dip, or brush, giving you flexibility depending on part size and volume. Its suitability for dip tanks is especially practical because components can be cleaned and protected in a single step, saving time in production or storage workflows.

Once the solvent evaporates, the product leaves a thin, dry, and slightly waxy film. Because the film is light-bodied and dry to the touch, it is less likely to attract dust or contaminate subsequent operations compared to oily or heavy-film rust preventatives, though you should confirm compatibility with any downstream coating, painting, or assembly processes.

TRUEGARD 304 provides up to twelve months of rust protection for metal parts stored indoors. It is not specified for outdoor or harsh-environment storage, so parts intended for outdoor exposure may require a heavier-duty product.

Yes. TRUEGARD 304 has water-displacing capabilities, meaning it can penetrate residual moisture left by water-based metalworking fluids and still form a high-quality protective film on those surfaces. This makes it well-suited for in-process and post-machining rust protection without requiring a separate drying step.

The product is rated for up to twelve months of reliable indoor protection. The listing does not specify performance ratings for outdoor exposure or extreme humidity, so for outdoor storage or highly corrosive environments a heavier rust preventative should be considered.

TRUEGARD 304 is a solvent-based fluid, which means adequate ventilation and appropriate personal protective equipment are typically required during application, particularly in enclosed spaces or dip tank operations. A Safety Data Sheet (SDS) is available from Truegard and should be reviewed before use to understand specific handling, storage, and disposal requirements.
