Marinette Bottom Paint

(not to be confused with barrier coat)

 

 

Until the mid 1990's most boats (fiberglass included) used anti-fouling paints containing Tri-butal- tin (TBT).  When this type of anti-fouling paint was outlawed by the EPA in the mid 1990's paints containing Cuprous-Oxide became the primary anti-foulant paints.  Unfortunately for aluminum hulled boats Cuprous-Oxide is not compatible.  Cuprous-Oxide will cause the aluminum hull to corrode and pitting will occur. 

 

Anti Fouling bottom paints containing Cuprous-Oxide should never be used on an aluminum hull.

 

There are anti fouling paints that are compatible with aluminum hulls.

 

Trilux 33  -  Available from Interlux (www.westmarine.com) is compatible with aluminum hulls and is the primary anti-foulant used on Marinettes.

 

EP-ZO -      Available from epaint (www.epaint.net) is compatible with aluminum hulls
