HIGH PERFORMANCE

NOTE: Northern High Performance Aluminum Cleaner is an industrial strength acid
cleaner designed specifically for cleaning aluminum parts in a dip tank. It is designed
to remove oxidation, other corrosion products and deposits. The Cleaner is a blend
of inorganic acids to provide the most complete corrosion and deposit removal with
the safest product possible. The acids in Northern High Performance Aluminum
Cleaner are inhibited to prevent excessive removal of base metal. Cleaner leaves
the aluminum bright and shiny with a satin finish. Pitted aluminum will look much
better after cleaning, but the pits will still be apparent. Aluminum with a mirror
finish will be given a satin finish as only polishing can restore the mirror look.
Northern High Performance Aluminum The Cleaner will remove the color from
anodized aluminum. This product is temperature sensitive and works twice as fast at
90º as 50º F. This product is concentrated and aluminum left exposed to the cleaner
for an extended period of time will etch and could dissolve. This product will etch glass
parts and attack various metals in different ways. Plastic, rubber and most paints are not
affected by it. Test first to be sure.

3. NORTHERN POWER LINER
Better Liner, Better Kit and Better Job!
As a truck bedliner...Our kit includes all the product necessary to
do an 8ft pickup box. Our competitor supplies 1 gallon of liner in their
kit. Then the instructions tell you to buy another quart.
When do you read the instructions? Right! Just before you do
the job. They tell you to buy another quart (really you need 2 quarts,
cause one won’t do the job). Then they tell you to use M.E.K to prep
the truck box. But you don’t get M.E.K. in their kit. So where do you
get M.E.K.? Quick now, your Saturday’s awasting!
Check it out...We include 6 quarts of liner. By the way, we use an
abrasive that doesn’t clump in the can. They don’t. And we include the
M.E.K and the tools!
Also Great for... Trailers, Boat Decks, Docks, Walkways, & Steps

to mate to red hot exhaust ports.
So check it out, what do you want on your HOT ROD?
If you want cheesy stuff, see our competitors. If you want all the horsepower you
paid for, see Northern! Here’s an untouched comparison photo of our 3/8” plate

AP90 HIGH STATIC PRESSURE
FAN & MOTOR
New High Static Pressure electric cooling fans developed to improve airflow in applications
such as diesel trucks, buses, racing and off-road vehicles.
The new AP90 High Output series fans overcome the high static pressure that results when a
large air mass is forced through a single or multi-stacked radiator core. As the flowing air is
restricted by the density of the core, a pressure differential occurs and the cooling fan must
work harder to overcome it.
