Customer Service/ Sales/Tech Line:
- CAN "I"
APPLY ANY OF THE COATINGS?
- Any professional
coating company, manufacturer, machine shop or professional engine
builder may purchase the products that we manufacture. In addition,
our products which either air dry or use water as the solvent
and are packaged for retail sale may be purchased by anyone for
- WHAT ARE THE
DIFFERENCES BETWEEN THE COATINGS PACKAGED FOR RETAIL SALE AND THOSE
WHICH ARE NOT?
- In almost
all cases there is no difference. The decision to package in retail
containers is based on the cure/solvent needed. Other than DFL-
1/TLML Dry Film Lubricants, all other retail packaged products
are the some ones that are used by professional shops. If it is
not available in aretail package, then it is "Shop Only"
due to contents and cure methods required.
- WHAT PARTS
SHOULD BE TREATED?
- Any part
subject to friction, loss of lubricating film, heat damage, corrosion
or abrasion. In addition enhanced appearance is possible for parts
such as headers, brackets, and suspension pieces.
- HOW MUCH POWER
WILL I GAIN?
- This will
depend upon many factors that will vary from application to application.
Testing has shown significant power increases on a dyno. In addition
certain changes can be made in such areas as tolerances, timing,
jetting and the lubricants used, that will increase torque and
H.P. and are only possible through the use of coatings. Horsepower
gains of up to 40h.p. have been measured in independent dyno testing.
- HOW LONG
WILL THE COATINGS LAST?
on the coating, part life increases from two (2) to ten (10) times
what is normal can be seen. In addition coatings such as CERMAKROME
can provide virtual lifetime protection against rust. The dry
film lubricants may burnish until they are no longer visible,
however, the active materials are bonded into the pores of the
part and continue to provideprotection.
- WILL I SEE
A TEMPERATURE CHANGE?
- Parts will
run cooler. Engine oil and water temperatures have shown a reduction.
On headers the radiated heat will be substantially reduced leading
to lower underhood temperatures and less heat absorption by nearby
- WHAT ABOUT
- The dry film
lubricants will burnish as they run until they are no longer visible.
They are applied at thicknesses ranging from .0005" to .0015".
However, before assembly the coating may be burnished back to
less than .0002" with gentle buffing using "Scotch-bright"
or similar material.NO CHANGES need to be made in clearances due
to the use of these coatings, though in many instances because
of the reduced part temperature and increased lubrication tighter
clearances may be run.
- WHAT ABOUT
- All machine
work should be done first.
- WHAT EQUIPMENT
- Parts first
must be sandblasted at low pressure (40 psi using a suction type
blaster) using fine sand (120 grit aluminum oxide is recommended),
NOT with glass bead. Then the part should be degreased using acetone,
lacquer thinner, M.E.K. or similar non petroleum based solvent
that leaves no residue. The coatings should be applied with an
airbrush or detail touchup gun. Baking may be accomplished with
any oven. Kitchen ovens or even toaster ovens work just fine.
Obviously the size of the oven will determine how large a part
can be coated and cured.
- DOES IT MATTER
HOW THICK I PUT THE COATINGS ON?
- YES, the
coatings are thickness sensitive. Generally .0015" is the
maximum thickness recommended. This thickness will be achieved
when a solid color is seen. Putting any coating on too thick can
cause the coating to crack, flake or bubble up.
- CAN I CURE
CERMAKROME ON MY CAR LIKE BLACK SATIN?
- No CERMAKROME
must be oven cured.
- CAN I SPRAY
CERMAKROME ON THEN TRANSPORT IT TO AN OVEN?
- While this
has been done, it is not recommended. You MUST first dry the coating
and then handle it very carefully. It is imperative that the coating
be sprayed on and then immediately dried and then baked. The coating
will absorb water from the air and if left sitting too long without
baking will become runny and no longer can be baked.
- WHY DOES
USING PKSX NOT HURT RING SEAL?
- The PKSX powder
only goes on 20 millionth of an inch thick. This does not fill
in the cross hatch. In fact PKSX actually improves ring breakin,
seal and long term leak down.
- WHY IS BLACK
SATIN A BETTER THERMAL BARRIER THANCERMAKROME, SINCE BLACK SHOULD
EMIT MORE HEAT THAN A SILVER COATING?
- While it
is true that black normally is a better color to emit heat, in
this instance the color is not as important as the fillers in
the coating. These fillers are very effective insulators, sufficiently
so that the black color does not affect the function. Interestingly
the silver color of CERMAKROME or any other Metallic Ceramic Coating
comes from the aluminum filler. Aluminum is a very good conductor
of heat. Yet the effectiveness of these coatings are not degraded.
- WHAT GUARANTEE
- All TECH
LINE products are guaranteed to be produced as described in our
literature. We cannot guarantee the performance of the products
as the use, application, and handling of the products is beyond
- CAN I USE
GLASS BEAD TO CLEAN MY PARTS?
- No: only
use fine sand or fine aluminum oxide. Glass bead is round and
while it is a good cleaner it closes the pores of the metal. Use
fine sand/aluminum oxide which etches the metal and cleans/opens
the pores allowing the coatings to bond into the metal.
- HOW FAR WILL
THE COATING GO?
on the more popular coatings are as follows: BHK, COLORGARD series and
TXBK small headers 4 oz.; medium headers 6-8 oz.; Large headers
10-12 oz.; CBC1, CBC2, and CBX 3oz is the equivalent of three (3) sets of small block
V8 pistons. DFL-1 covers the major parts of a V8. PKSX requires
only a small amount of powder to do all the surfaces in several
engines. In all cases a little material goes a longway.
- WHAT SHOULD
I USE TO SPRAY IT ON?
- Use either
an airbrush (not one for pinstriping) or a detail touch-up gun
(jam gun). Larger spray units or aerosol spray jars are not recommended.
Most coatings spray with 35 psi. The water based coatings work
better at 50 to 60 psi.
- WHAT TUNING
CHANGES WILL BE NECESSARY?
- The changes
necessary will vary from engine to engine and depend on how many
parts are coated. In general coating the combustion chamber surfaces
will allow you to run less initial timing with no loss of power
(usually a gain will occur). You may also be able to run significantly
less fuel, due to the more efficient oxidation that occurs with
the coated parts. You should be able to run smaller jet sizes.
Obviously no specific recommendations can be made as every engine/combination
will be different.
- HOW DO I
TELL IF I HAVE THE RIGHT THICKNESS OF COATING?
- In general
the easiest way to tell is by appearance. When you have solid color
you have sufficient material. One solid coat is better than several
light coats. You can overlap the coatings during application, but
it is best not to let the parts dry before putting more material
over a coated surface. Do not judge coatings the way you would a
coat of paint. The coatings go on from 1/3 to 1/5 the thickness
of a coat of paint.
- WHAT SOLVENTS
SHOULD I USE?
- Use any
solvent that does not leave a residue. Acetone, M.E. K. and lacquer
thinner usually work well. DO NOT USE PETROLEUM BASED SOLVENTS.
- WHAT DO I
USE TO POLISH CERMAKROME?
- Use fine
steel wool or 600 grit wet/dry sandpaper. A final polish with
a buffing wheel or 1200 grit sandpaper, or a polishing compound
will bring a very bright shine. Do not use “Scotch-bright” or
similar material. Lightly glass beading at about 25 to 30 psi
will give a nice effect and it is easier to polish up after glass
beading has occurred.
