How can you prevent forms from rusting?

The correct method to prevent forms from rusting involves the application of mineral spirits. Mineral spirits are solvents that can help clean and prepare surfaces, but their primary function in this context is to aid in the application of protective coatings. When surfaces, especially metal forms, are treated with mineral spirits, it enhances the adhesion and effectiveness of protective sealants or coatings that can then be applied to prevent rust.

Using oil-based paints is also a common technique to protect metal from rust, but applying mineral spirits is more about preparing the surface and ensuring that any subsequent protective layers adhere well. Covering with plastic sheeting provides a barrier against moisture, which is a major contributor to rust, yet it may not be as effective alone without a proper protective coating underneath. Regular oiling with vegetable oil is generally not suitable as a long-term rust prevention method because vegetable oils can degrade over time and may not provide the necessary protective barrier that mineral spirits combined with a suitable coating can offer.
