Advance Coating Practice Test

Stripe coats target protection where geometry makes coating coverage tricky. Edges, corners, welds, and complex geometric shapes create corners, crevices, and transitions that are hard for a regular spray to cover evenly. By applying a stripe coat—a narrow, targeted layer—you ensure a sufficient film thickness right at those critical features. This helps prevent bare spots, improves adhesion, and enhances corrosion resistance when subsequent coats are added or when the coating builds up. In contrast, flat surfaces and large flat areas are easier to cover uniformly with a full coat, and inside cavities pose access challenges, so they’re not the typical focus of stripe coating.
