Paint Benefits and Limitations
- A good paint provides durability, corrosion resistance, and weather resistance.
- The main limitations of enamel paint are its high gloss finish, tendency to yellow over time, and brittleness.
- The main components of an excellent-quality paint mix are binder, solvent, pigment, and additives.
Paint Coatings and Surface Preparation
