Powder Coating
So I couldn’t find a paint section to post this to, so here it is. My project is going to be powder coating various pieces of my Harley. My major one is going to be the Jugs. Along with the lower legs, trees, bars, so on and so on. So I’m here looking for any input as to metal temps, and especially any help on picking the right powder. I want to have a really shiny black finish thought the bike.
I am using craftsman gun, and going to bake in an oven at home. I know I need a high temp powder for the engine. Anyone have any tips or DIY instructions.
Another bit to chew on. I read a magazine the other day saying "you can powder coat over chrome". What are ya’lls thoughts or experience?
Thanks,
Joe

Sarge,
Considering the amount of work you are looking to do, and how much work will be required when the finish fails, I would take that stuff to a pro. By all means do the brackets and other parts that can easily be removed if there are problems. However, do NOT use the oven you intend to use again for food!!! There are VOC's given off during the curing process that will coat the inside of the oven and basically poison your food... even if just slightly. Get a dedicated oven or don't do it.

I have picked up some powder from east coat and am using a fine glass bead in a blasting cabinet along with a wire wheel to scuff the surface. i have a little orange peel on the parts i've done so far but that was without outgassing the parts. We're building a booth tomorrow and I should be spraying powder next weekend or the following weekend. Based on the idea that my powder was a total of $100 and the coater I went to see wanted $300 to even look at doing my parts (black base with a clear/flake mid coat and a clear top coat) After working in the paint shop in the KC Harley plant for a year, I've found that you can black powder over ALOT of things. Scuff the surface of your chrome to make it look more like brushed aluminum and then clean them.. and then clean them again and again. Throw them in the oven at 400 for 10 minutes, pull them out and let them sit for 3-4 minutes. Spray your powder and put them in at 450. when they flow out drop the temp to 400 and bake for 15 minutes. (those are the hot coat directions- different powders have different instructions and clear has a lower temp) get plenty of powder and plenty of practice parts and have fun!! look up orange peel in powder because there are 1000 different aspects that will cause it. Make sure your gun pressure is very low etc.
Later and good luck

Powdercoater, thanks for your concerns and comment. Im kinda a hard head and want to do everything on my bike myself. When some one asks you who did this or that on your bike, I am going to be able to say I did it. Not some dude at a shop. Thats whats its all about man.
ky_ace, thanks for your help to man. Is your powder from a company called east coast?? Any luck with the new booth?
I did email a shop to kinda get an idea of what they are using to get a better feal before I tackle my project. They said I wont need a high temp powder for doing the engine. They said I only need that for the pipes. Any thoughts.
What is the standard running temp of a air cooled v-twin, anyone?
Need to get home so I can start the project, till then Im stuck spreading democracy in Iraq.
