I'm about 3 hours into my first powdercoating adventure. Man, this stuff rocks. Again, Ginter is right. If you have a garage, and don't have your own setup - you might want to rethink that.
My setup from Columbia Coating, including about 8 pounds of various metallics/clears was about 200 bucks. Pam picked up some extra natural corks (because she saw it on American Chopper). They seem to work as well as the synthetic/plastic corks for plugging bolt holes. I will post pictures later... gotta get back out and monitor temps. -Rusty (IMG:style_emoticons/default/smoke.gif) |

I removed the entire front suspension, and took it to Pam's garage, where we're doing the powdercoating.
For heat, we're using a 28,000 BTU propane heater. It's not ideal, but it's a solution if you don't have 220 power in your garage. Pictures soon. -Rusty (IMG:style_emoticons/default/smoke.gif) P.S. You joke about the sun, but that's actually been done. Ask Ginter for the details - I don't remember enough of the story to tell it correctly. |

Yup. A guy sent me pics of an old Weber BBQ grill with sides he built and painted it all black. Powdered his parts and placed them in the grill in the sun for the afternoon. He said it had been years since he coated them and they were still mint.

Finer details really depend on the powder used (spec sheet will tell you). But generally speaking 400F +/- for 20 minutes after flow out. Flowout is when the powder liquefies and turns to a glossy finish (that's how you tell it has occurred). Flow out usually takes around 5 minutes, but that is dependent on the size (mass) of the part.

Please, tell me more (IMG:style_emoticons/default/pray.gif)
I have access to two desicant ovens at work. Nothing like a goverment job after hours (IMG:style_emoticons/default/beer.gif) No wonder a guy about 20 miles away only wants 30 bucks to do a couple of parts. |

It's not hard or technically challenging. It can be tedious though. Trying not to knock your part or blow or knock the powder off the part while getting it in the oven, stuff like that. It's almost not worth your labor as compared to having it done professionally. Unless you're really cheap. On the other hand, it's nice to do it yourself. And handy to be able to blast and powder coat anything you want even at a moments notice.
Pull a rusty metal part off the car during routine maintenance? No problem! Bead blast, powder and bake! |

It does help if you have the resources to do it yourself......
Besides, I'd love to know how to do it myself. It's like brewing your own beer, the first few batches are fun, then it turns into a pain in the ass.... (IMG:style_emoticons/default/beer.gif) |

(IMG:style_emoticons/default/laugh.gif) Good going, LB. I've thought of trying the gas heater idea also. It would be pretty easy to make a reflective hood to help heat the parts uniformly and not have to rotate them as much. Can anyone report on how well it works on aluminum? |

To do this in an oven, it needs to be electric? Gas won't work?

I saw some pics on a site that showed them cureing with a round propane heater on the top of a 20lbs tank. They were using a piece of plywood as a reflector. Think I bookmarked it, but I'm at work now. Will look tomorrow.

Plywood as a reflector for a propane heater? Sounds a little iffy to me.

My source for powdercoating is:
Columbia Coatings Their website needs some professional help, but the product is good. If you check the Online Store for the Chicago Electric powder kit, it's the best deal. $135.00. It comes with powder, PC masking tape (the good green stuff), plugs of various sizes and hooks. Attached image(s) |

I wonder if a gas grille could be used? You could potentially put some sheet metal, slab of slate/rock/brick or whatever over the grille area to even out the heat. Or just get it super hot and then turn off the burners. My grille has ceramic tiles that absorb and radiate quite a bit of heat after the flame is off.

A gas grille would be good, if you could find an old one.
The key is keeping a steady temp. I'm checking that thermometer every 2-3 minutes (Walmart, about 2 bucks.) Sorry no pics yet. I forgot my camera-to-computer cable. Plywood as a heat reflector sounds like a recipie for fire. I'm using heavy grade sheet steel. |
