Thank you, for your interest in Classic Blast, a new sandblasting process developed to provide a better,
cheaper, and safer way to remove old paint and rust from classic parts.
In the early l990’s, I began testing various blends of abrasive materials to improve cleaning performance for fabricated steel.
After testing literally hundreds of media combinations, I discovered a special blend that increased blasting speed
and reduced material costs by over half.
As word spread about the exceptional performance of my new blasting method a new market developed...
the cleaning of classic parts. I was pleased to find that my new customers were more interested in quality results than low price.
During the last 10 years I have made many improvements in the original Classic Blast concept.
I have perfected several abrasive blends that work better at low pressure and basically redesigned
my blasting equipment from the ground up. What I have now I consider, one of the best and most effective
ways to clean classic parts for re-painting
After you read the following material contact me again for questions or pricing.

Classic Blast is a low pressure / low impact abrasive cleaning process that uses several blends of hard dense
minerals and an exact percentage of graded walnut shells.
CLASSIC BLAST PERFORMANCE IS BASED ON THE FOLLOWING RATIOS..
-40% due to the Classic Blast media blend.
-40% due to the training and experience of the Classic Blast operator.
-20% due to special equipment modification
-Produces an exceptionally clean and smooth metal surface
-Virtually eliminates, pitting, warping, or excessive surface roughness.
-Produces a “Super Clean” metal surface that prevents rusting for months
-Eliminates the need for hurry up priming)
-No need to sand. Primer can be applied directly over smooth cleaned metal
-Economical. Classic Blast can be recycled up to 25 times.
-Reduces waste and disposal costs up to 90%
-Low pressure operation reduces worker fatigue and equipment wear
-Improves painting quality and performance.
-Excellent part time or full time business opportunity.
One of the major advantages for Classic Blast is its excellent cost to profit ratio.
Below is a comparison between Classic Blast media and common silica sand.
Silica Sand at $ 5.00 per 80lb bag
Classic Blast media at $25.00 per 50lb bucket
If you use silica sand at a rate of 800 lbs hr, 8 hrs day, 5 days wk you will use 32,000 lbs
32,000 lbs x six cents per lb = $1920.00 per week cost
Material Cost Per Day = $384.00
If you use Classic Blast media at a rate of 200 lbs hr x 8 hrs x 5 days you will use 8000lbs
Recycled 25 times = net material usage 320 lbs. per week
320 lbs x 50 cents = $160.00 per week cost
Material Cost Per Day = $32.00
Note: I have found after I use Classic Blast media 10 times I can add as little as 25 pounds per day($12.50)
and never run out of productive material.
Below is a list of the major items needed for Classic Blast operations.
You will need a good running electric, gas, or diesel air compressor capable of producing a minimum of 25 cubic feet per minute (CFM).
Smaller units can be used but, removal rates will be much slower.
SANDBLAST “POT” OR CABINET
Most manufactured sandblast pots or cabinets will work with Classic Blast media
MOISTURE & OIL SEPARATOR
Since the Classic Blast media blend is very dense and heavy (125 lbs per cubic foot),
it is critical to remove all moisture and oil residue from air to insure constant media flow.
AIR VENTURI HV BLAST NOZZLE
This is a must have item for Classic Blast. This nozzle has a series of air induction holes in its body that mix
compressor air with atmospheric air. Because Classic Blast operates at low pressure (25 to 50 psi), the venturi
action is necessary to insure constant media flow at low pressure.
BLAST POT OR CABINET AIR PRESSURE GAUGE
It is very important to accurately set air pressure levels for Classic Blast cleaning. This is done to avoid damage
to thin gauge metal parts. The external pressure gauge allows air pressure to be set at per pounds used. After the
pressure is set, it is not necessary to readjust just, use the original shut-off valve to turn the pot off and on.
This structure is used to capture Classic Blast media for recycling. This area should be at lest 25 x 25 feet
to allow enough room for classic cars, tractors, and other large projects.
CLASSIC BLAST MEDIA RECLAIMER
When I first started using Classic Blast, I used common screen wire to sift used material but, after several times
increased amounts of dust, dirt, and paint chips began to reduce cleaning performance. Finally, I designed a small,
but, very effective, media cleaning device based on air wash and gravity separation principals. This device is very effective for removing contamination from used media for increased recycle potential.
SARA PAINT STRIPPER
I have found that many classic body parts have been repainted several times. The extra coats make abrasive cleaning
difficult even with Classic Blast media. I now use a new stripper from Canada based on SARA technology (selective adhesion release agent). Sara strippers are non toxic and safe to handle. I remove extra coats until I get down to the original paint then, finish up with Classic Blast. This saves time and material. . Note. SARA paint stripper can also be used on plastic or fiberglass.
