First of all, it is POWDER coat, not powerder coat.

The following is straight from wikipedia.com

"Part Preparation Processes & Equipment
Removal of oil, soil, lubrication greases, metal oxides, welding scales etc. is essential prior to the powder coating process. It can be done by a variety of chemical and mechanical methods. The selection of the method depends on the size and the material of the part to be powder coated, the type of soil to be removed and the performance requirement of the finished product.

Another method of preparing the surface prior to coating is known as media blasting or Abrasive Blasting. Blast media and blasting abrasives are used to provide surface texturing, etching, finishing, and degreasing for products made of wood, plastic, or glass. The most important properties to consider are chemical composition and density; particle shape and size; and impact resistance.

Silicon carbide grit blast media is brittle, sharp, and suitable for grinding metals and low-tensile strength, non-metallic materials. Plastic media blast equipment uses plastic abrasives that are sensitive to substrates such as aluminum, but still suitable for de-coating and surface finishing. Sand blast media uses high-purity crystals that have low-metal content. Glass bead blast media contains glass beads of various sizes.

Different powder coating applications can require alternative methods of preparation such as abrasive blasting prior to coating. The online consumer market typically offers media blasting services coupled with their coating services at additional costs."

Contact this guy (http://contour.org/ceg-vb/showthread.php?t=27135&highlight=powder+coating) and just have him do it. He looks like he does a good job and I will be sending some parts to him in the future.

If you don't already have the equipment to do it, I looked into it and you would have to have quite a need to do a lot of parts before it really became beneficial to get your own gun, dedicated oven and all that good stuff.

Hey ModCougar, isn't that directly out of Wikipedia? I coulda swore I've read that before there.

Yes, sir. Amazing what a little searching can do. Lol.

I should probably go back and add that in that it was from wiki...

-glass bead
- clean
-blow out bead as much as poss
-then there is a prep cleaner you apply and bake it with to get all oil and grease off
-apply black powder coat ( chrome has to have black first ;) )
-bake
-apply chrome
-bake
- then blow out rest of stuff that might be inside...... its always important to blow stuff out that was powder coated......no matter how good a guy is there is always places bead and what not can get stuck or lodged...take the time to blow part out before install..... dont want sand dont in your motor right ;)


and powder coated stuff can be cleaned with soap and water when it gets dirty :)
