FAQs

SHOULD I CLEAN MY PARTS?
It is best to bring parts in reasonably clean.  Heavy grease and oils must be removed before we can sandblast or move parts through our pretreatment systems.  Sandblasting greasy parts pounds grease into the faq_imagemetal parts and contaminates our blasting media, as well as, heavy oils will contaminate chemicals in pretreatment systems. We can clean excessive grease manually at an additional cost if you are unable to.  Rust and paint are not an issue. Small automotive and motorcycle parts are run through an ultrasonic “parts” cleaner prior to the final cleaning treatment before powder coating.

CAN I USE BODY FILLERS?
Convention fillers such as bondo, or other resin and plastic fillers cannot stand up to oven temperatures. Generally the powder will not bind to the filler surface and may cause bubbles or discoloration in the finish. Any fillers should have a metal base and be tested prior to coating.  
  
WILL POWDER COATING FILL IMPERFECTIONS IN THE METAL?
Powder coating will generally not fill in noticeable scratches or pitting in the surface. Although thicker than most paints, when powder flows out like paint, it will take the shape of the surface.   
  
DO PARTS NEED TO BE DISASSEMBLED?
With a few exceptions, parts should be completely disassembled, especially used automotive & motorcycle parts. To prevent clearance issues your item can be masked and plugged. All bearing and bushings should be removed if possible as they can hold oil that liquefies and flows out during the oven curing process ruining the final finish. 
        
WILL THE HEAT USED TO CURE POWDER EFFECT MY PARTS?
Powder is cured normally at 375 and 400 degrees; this should not affect most parts. Some vintage automotive parts, such as fuel tanks, were bonded with solder that can liquefy at curing temperature. There are other exceptions we can discuss.    

WHAT ABOUT THREADED PARTS AND AREAS I DON'T WANT POWDER?
Surfaces such as machined areas on intake manifolds are masked with high temperature tape designed for this use. Threaded holes and studs are either plugged or masked.

CAN I POWDER COAT OVER AN EXISTING POWDER COATED FINSH?
It is always preferable to start with a fresh raw metal properly cleaned and treated before powder coating. There are times we can coat over a previously coated finish depending on the condition of the original finish. Coating over an existing powder coating is not recommended and the outcome not guaranteed.   

CAN I POWDER COAT CHROME PARTS?
Yes, providing it is good quality chrome plating in good condition. We clean and lightly haze chrome with media blaster to roughen up the surface for adhesion. However, there is a rare chance the chrome can lift from the base plating. This is out of our control and would require it to be removed by a chrome plater.

DO YOU HAVE A MINIMUM CHARGE OR NUMBER OF PARTS?
There is no minimum required for the number of parts. We go into a wide array of colors each week and generally consolidate jobs of the same color together to avoid additional charges to our customers. If you are selecting a color that not common or are unable to wait for us to work your part into our normal powder coating schedule then a low minimum fee may apply.

CAN YOU REMOVE MY TIRES AND WHEELS?
We do not perform mechanical work. Wheels need to have tires removed prior to the work required.

WHAT IS OUTGASSING AND HOW DOES IT EFFECT MY PARTS?
Out gassing can occur in casted parts.  Cast parts are made by pouring molten material into a mold or cast. Air can become trapped during the process. This air is sometimes released when parts are heated during the powder coating curing process creating small bumps, bubbles, or holes in the finish. At Temecula Valley Powder Coating cast parts are prebaked in our oven to release trapped air prior to powder coating. Sometimes outgassing may still appear although all steps have been taken to prevent it. Though rare this sometimes happens in lower quality castings.

CAN I MATCH AN EXISTING PAINT COLOR?
Powder is available in hundreds of colors. It is sometimes difficult to get an exact match. Exact custom colors can be manufactured, however, the cost is usually prohibitive and reserved for large volume commercial customers due to the amount of powder that must be ordered. There are smaller color matching services available and powder coaters who claim to offer color matching. Smaller batches must be "dry mixed" from existing colors and the discerning customer is usually not satisfied with the result being just a different shade of close. It is easy to match paint colors to powder coating at the local automotive paint store.
