Cleaning of contaminated antifouling
For hard polishing and ablative antifoul-
ing paints that have been heavily con-
taminated the best method to use
when treating the bottom is to use a
paint-stripper such as Interstrip 299e to
remove all the pollution and the paint,
then scrub the substrate using Fiber-
glass Surface Prep YMA601 and a
coarse Scotch-Brite pad. Rinse with
fresh water. Repeat until the surface is
clean (when the water cascades off of
the surface with no beading or separat-
ing). Allow the surface to dry thoroughly
prior to re-painting. The same process
is recommended on metal boats how-
ever to avoid corrosion the metal sub-
strate should be prepared by grinding
or blasting after the cleaning process
and prior to priming. To aid adhesion
apply InterProtect 2000E primer per
label instructions.
Sanding or sand blasting a surface that
still has oil on it may drive the oil into
the surface and cause a loss of adhe-
sion of the subsequent coats.
If the coating of oil is light, power wash
and then use a household detergent
with water to scrub off any pollution.
Then scrub using Fiberglass Surface
Prep YMA601 and a coarse Scotch-
Brite pad and rinse thoroughly with
fresh water. Let dry prior to re-painting.
Polishing paints such as Micron Tech-
nology, may be re-launched without
painting assuming the film thickness of
remaining paint is adequate (2-3 mils
dry after scrubbing) & the next applica-
tion is scheduled within 5 months.
Cleaning of contaminated topcoat sur-
Contaminated topcoats should be
cleaned as soon as practically possible
to minimize the damaging effects of
the crude. If the surface of a topcoat is
contaminated with crude oil, staining
and possible degradation of the topcoat
may result from the acidic nature of the
contaminant. The recommendations
below apply to Awlgrip
, Awlcraft
2000, and Interlux
Perfection top-
coats. If there is any doubt of the type
of surface in question always test a
small area first.
In the case of heavy contamination, the
material may be a thick, sticky tar-like
material due to its exposure to the ele-
ments. It is recommended that these
surfaces first be cleared by wipe down
with T0016, T0170 or Mineral Spirits
followed by power washing, and then
cleaned with Awlwash® at a 4 oz./
gallon level (or household liquid deter-
gents such as Dawn). The detergent
washing step of the cleaning process
must be done in manageable areas.
Each area should be then be thoroughly
rinsed with plenty of clean water before
moving on to the next. DO NOT allow
detergent solutions to dry on the sur-
Hulls exhibiting ‘sheen’ contamination
may be cleaned with the regular con-
centration levels of Awlwash, though
they too may benefit from a prewash
wipe down with T0016, T0170 or Min-
eral Spirits to loosen the film.
In both cases, it is recommended that
the newly cleaned surface be protected
from further contamination with appli-
cation of Awlcare®.
Contaminated waste water should be
collected per local marina guidelines,
local authority regulations and/or Clean
Water Act requirements. Collecting the
water and the emulsified crude will pre-
vent spreading of contamination. Crude
and solvent contaminated wipes must
also be disposed of in a responsible

Market Research Predicts
Rebound in Boat Sales
Recent analysis from the
, a marketing research firm
based in Cleveland OH, predicts an i
crease in U.S. boating market sales
with demand rising 9.3 percent ann
ally reaching 10.1 billion by 2014. T
includes boats, propulsion systems
Demand will be driven by gains in co
sumer spending and disposable in-
come, while the recovery in financial
markets will enable more consumer
buy boats on credit. Growth in the 5
64 age bracket will also support de-
mand, since boat purchases becom
more likely just prior to retirement
(although they tend to decline there
ter) and consumers in that age grou
have the disposable income to pur-
chase larger, more expensive vessel
In addition, the industry’s effort to m
ket the “boating lifestyle” to women
and minorities should expand the m
ket. However, even with the rapid sa
growth, the market is not expected t
recover to the pre-downturn levels u
the end of the decade.
These and other trends are presente
