How do I ensure the finished project has sufficient mil coverage?

The most accurate way to measure dry film thickness is to use a mil gauge. Apply an appropriate number of coats to achieve the desired dft for the appropriate protection for your project. Refer to the chart below to determine the theoretical coverage of Rust Bullet Coatings (70% solids by volume). This theoretical coverage does not take into account transfer efficiency which will vary dependent upon application equipment, applicator and atmospheric conditions during application. The number of coats needed to achieve the appropriate dft will depend on the chosen method of application: brush, roller, HVLP Spray System or Airless Spray System.
