Buying Guide: Bilge Paint Decisions
- What is the main purpose of bilge paint?
- Protection against water, oil, and solvents; ease of inspection; and brightening of the bilge space.
- Epoxy vs. non-epoxy: Which should I pick?
- Epoxy-based bilge paints offer superior chemical resistance and durability, making them ideal for engine rooms and heavily used bilges.
- Color choice: Gray or White?
- White can brighten spaces and reveal leaks; gray hides minor stains and blends with engine components.
- Finish and application: What’s practical?
- Most bilge paints require 1-2 coats; surface prep and priming are critical for adhesion on metal, fiberglass, and wood.
- Size and budgeting: When to pick gallons vs. quarts?
- Quarts fit smaller spaces or touch-ups; gallons cover larger bilges but require more mixing and curing considerations.
