STRIPPING POWDERCOATED SPRINT CAR FRAME WITH THERMAL PROCESSING AND ABRASIVE BLASTING
The sprint car frame pictured above was originally powdercoated. As shown in the top row pictures, it has now been thermally processed and is setting in the blast room. The whitish gray color is fly-ash with some minor redish colored rust towards the front. This frame was stripped under our self-serve option threw a local powdercoating company. The lower row of photos is after an abrasive blast with 60/120 black magnum. On this project, a class B- surface was acceptable and desired by the customer in order to maintain tight process scheduling and cost structures set by his customer. We think he did pretty good. The total cost of the thermal was $95.00 and the total self-serve process time ran 1.6 hours. Turnaround on the total project baked, blasted, recoated and delivered back to owner, less than 48 hours. The powedercoater charged his customer $250.00 for the stripping on the chassis, so he's not hurting and we would most likely have charged closer to $325.00 for a better grade A finish. All the same, if the frame had not been previously powdercoated, the added expense of thermal processing may have been avoidable. This project completed Feb. 13, 2003. Please contact us with any questions you may have and thanks for looking.
THERMAL PROCESS PAINT REMOVAL BY THE BASKET ON THESE 1972 CHEVY CHEVELLE PARTS
BASKET CONTAINING 1972 CHEVELLE FENDERS DOORS WHEEL WELLS AND DECK LID
This basket of 1972 chevy chevelle parts have been thermally processed. The white, yellow and pink areas are fly-ash left by the baking process. The darker red and brown patches are rust and what's left of any undercoating materials. Not everybody with a bake oven should attempt to process heavily coated, easily destroyed, automotive panels or entire car bodies for that matter. It takes specialized computer controlled systems which monitor and respond to increased afterburner temperatures and keep deviations in process temperatures within 25 degrees of the predicted ramp and soak settings. Most ovens don't have adequate controls to prevent unexpected conditions and self correct process deviations that can damage or destroy your parts.
These parts can now be blasted with abrasive such as black magnum (grade A), mild abrasive such as glass bead (grade B), non-abrasive such as walnut shells or corn cob grit (grade C), or powerwashed and manually d/a sanded (grade D). As always, price constraints will dictate the quality that can be provided. Typical basket prices for this service will be $95.00 per basket as pictured. Thermal processing your parts before stripping will save many times the expense no matter what system you choose to finish the job with. These parts were thermally process on Feb. 10, 2003 for a private individual restoring this car for his personal use.
Pictured below are the parts after abrasively blasting to a grade D finish under a self-serve strip agreement. They don't look particularily pretty, however, they were exceptionally affordable. The total cost to customer was less than $60.00 excluding the cost of the bake. We don't mind telling you, if these same parts (2 fenders, 2 wheel wells, 2 doors, and 1deck lid) had been cleaned to white metal the cost could easily have been $450.00 and instead of 2 hours probably closer to 8.

The above pictures show various stages of paint removal on this 1957 Dodge truck. We began to strip this vehicle Feb. 14, 2003 under a self-serve strip agreement. As with many projects, we start with a thermal process to remove multiple layers of paint and body fillers. The bake on the cab body cost the customer $95.00 but paid for itself many times over with increased stripping speed. A basket of related parts including ( 2 doors, 2 inner fenders, 2 fenders, a radiator housing, a front nose valence with head light doors, and several small pieces were also thermally processed at an additional cost of $95.00 for one basket.
The smaller parts were cleaned via abrasive blasting with fine black magnum in our large cabinet blaster. As pictured they were stripped to a grade B+ surface. The cab body was abrasively blasted to a B+ surface on all but the inner top and rear panels which were prepared to grade C. The cab body, front nose valence and both doors were cleaned in the blast room. The total cost for the cab body and all related parts came to $330.00 as pictured excluding the cost of thermally processing. Next we will be coating the cab body and most major components with an epoxy powdercoat primer and will display these pictures and pricing as soon as they are available.
EPOXY POWDERCOATING ON 1957 DODGE TRUCK AFTER ABRASIVE BLASTING FOR EXTREME RESISTANCE TO CORROSION
The following pictures are the same project shown above. The entire project below has been epoxy powdercoated. Epoxy is extremely durable and resistant to most chemicals. Powdercoating is one of the most protective coatings available today and is certainly the most difficult to strip. Put epoxy powdercoating on anything and it should outlast everything else out there.
While epoxy powdercoating is not cheap, it is certainly affordable. The total cost to customer for epoxy powdercoating the cab body, fenders, doors, gas tank, front valence, and 12 smaller pieces was $780.00 and is comparable to what a wet coat epoxy or etching primer would run when applied by a qualified body shop. This is the highest level of quality available in the restoration stripping and priming services arena.
In this case, the epoxy powdercoating is being used as an underlayment and will be top coated with conventional bodyshop paint and primers. We recommend removal with a grinder if the area in question is to receive susbstantial amounts of fillers or for welding and metal replacement sectionals. Otherwise simply scuff or wet sand to remove the gloss and you're ready for topcoating. We also offer a complete powdercoat refinishing service on automotive, motorcycle, race car chassis and many other items well suited to powdercoating.
We would like to point out that while pricing is similar to wet coating, powdercoating allows us to coat areas that conventional spray guns cannot reach. On this project, specifically the entire inside of the door shells has been completely coated and many areas on the cab body, like under the dash and behind support beams, cannot be done any other way and insure proper coverage.
STRIPPING AND RUST REMOVAL ON HARLEY DAVIDSON MOTORCYLE PARTS
To the right are pictures of a Harley Davidson motorcycle tank after thermal processing. You can still see the outline and differential in color where the stickers used to be. The purple pearl paint has been reduced to ash and rust which had been covered by paint is now clearly visible. After a white metal blast using 60/120 black magnum, this tank is as good as new.

MOTORCYCLE FENDERS BEFORE
To the left are both fenders to match the above tank. They were both stripped the same as the tank and are now ready for refinishing. The tank and two fenders were thermally processed for the minimum $25.00 charge and then stripped in our large abrasive cabinet. Total blast labor was 1.1 hours at $40.00 per hour. Total charges ran $78.00 to this local motorcycle restoration shop. Work completed Feb. 13, 2003.
