The direct answer is Yes.
Sea Hawk Tuff Stuff Epoxy Primer is an effective water barrier and universal primer. When applied to metal hulled boats it can serve as corrosion protection below the waterline. Therefore many boaters want to have that sort of protection on their Jon boat, and apply Aluma Hawk Boat Paint on top.
When over-coating Tuff Stuff Epoxy Primer it is important to meet the required over coating times in order to achieve the best adhesion because temperature and humidity have a direct impact on dry times. QUICK and EASY RULE: When the coating is dry to the touch, yet still has some tack, it is ready to be over coated. Your thumb will leave a print without lifting any epoxy. This is called hot-coating. However, if the coating is completely cured (or after 24 hours) it needs to be thoroughly sanded with 80 grit sand paper to remove the shine, or you must apply another coat of Tuff Stuff within 6 days. Then you have an additional 24 hour maximum window to overcoat with paint.
These two products are great on their own, but they can do so much more when working in conjunction with each other.
