Sea Hawk Tuff Stuff is an extremely high-build two-part marine epoxy primer that dries fast, enabling application of a complete barrier system and bottom paint in just two days. Using microsheet silicate technology, millions of microscopic sheets overlap and build a 100% water barrier that protects the surface from moisture and water penetration.
Tuff Stuff is extremely effective for blister prevention on fiberglass, or as a bilge coating, because it is resistant to oil and water. As a universal primer, it can be used for corrosion protection on most metals below the waterline, and for priming any metal. Tuff Stuff creates an overlapping barrier to eliminate any direct path for water migration.
NOTE:Cannot be sold to California residents.

Barrier Coat Primer
what is used as a top coat and can this be used on a boat trailer axle that doesn't go in saltwater often?
Henry,this product is listed as a primer, not a topcoat. I would like to know what I can use for a finish coat and would it then fade? without a top coat the finish will fade.thanks,van...
Yes I will use this product on my trailer axle. I have use tuff stuff as a top coat for my boat engine, work grate , would definitely recommend this product.
how much coverage?
About 150sqft per gallon.
Great stuff for repairing damaged tub surface
I used the product on an old tub, in this case, not a slow boat but a jetted tub. The bottom of the tub had scores of microfissures. While it was not leaking--yet--it was only a matter of time before it would. The three coats of product went on beautifully after careful prepping of the surface with 150 grit paper, Lime Away to dissolve scale, acetone to remove grease etc, and a tack rag to remove sanding dust. I followed this primer with three coats of Rustoleum Tub and tile paint. That was not nearly as tough or highbuild as the Tuff Stuff. If I had to do it again--perish the thought--I would use a high quality marine epoxy. So far, so good. I am very happy with the results.
