- 2-Part strontium chromate epoxy base coat creates a super-thin layer barrier that provies maximum protection against corrosion, chemical, and moisture damage on aluminum and steel boats
- Use it to prevent corrosion on aluminum masts, booms, bowsprits, spreaders, T-tops, railings, and more
- Inhibits corrosion on other underwater metals such as trim tabs, shafts, and struts, preventing unsightly pitting
- Functions as a highly effective tie-coat primer, providing a superior bonding surface for topcoats or other primers
- Ideal for corrosion protection on large surface areas
- Simple 1:1 mix ratio (by volume)
- Easy to apply by spray (recommended), brush, or roller
- Use above and below the waterline on properly prepared aluminum, steel, and sanded fiberglass

One thin coat provides excellent adhesion and corrosion protection for metal boats and boat parts
TotalBoat Strontium Chromate Epoxy Primer is specially formulated to prevent corrosion on metal boat surfaces. It is ideally suited for use on duck boats, aluminum boats, pontoons, & steel boats. This protective primer creates a barrier impervious to moisture and chemicals that not only protects the metal under it, but gives urethane topcoats and epoxy primer overcoats a surface they can really stick to. Strontium Chromate Epoxy Primer is great for more than just metal hulls—use it on aluminum spars and underwater metals, too.
Etch now or kvetch later
Bare aluminum oxidizes very quickly, which is OK if you don’t plan to paint it. But the oxidation that protects unpainted aluminum from corrosion makes paint or primer peel faster than a banana at a speed eating contest. Well maybe not quite that fast, but since there’s nothing appealing about peeling, we recommend treating aluminum surfaces with our TotalBoat Aluminum Boat Etch Wash first. It removes oxidation n just five minutes, and creates the etched surface necessary for successful adhesion. After the surface has been rinsed and dried completely, apply Strontium Chromate Epoxy Primer immediately.
In fact, timing is everything with this easy-to-use primer. Plan to complete the entire surface prep process and application of 1 thin coat of TotalBoat Strontium Chromate Epoxy Primer within 4 hours, if possible, to prevent oxidation or surface contamination.
Note: Not meant to fill surface imperfections
TotalBoat Strontium Chromate Primer is a thin tie coat to be used for corrosion protection and adhesion—it does not fill surface defects. To fill small scratches and other minor surface imperfections, apply TotalBoat 2-Part High Build Epoxy Primer within 45 minutes to 48 hours of applying Strontium Chromate Epoxy Primer.
