Powdercoating! :-)
I finally found a cheap oven and tested my first peice for powdercoating using the Eastwood Hotcoat gun.
This is my alternator bracket. I really liked the results and am going to be powdercoating as many of the parts as I can. Of course, this will extend my project a little longer. :D

I'm pretty pleased with their kit Pat. It is surprisingly easy and foolproof (so far). I just need to extend my oven so I can do larger things now. I'm going to do a valve cover today to see how it looks and I'll post the pics.

Re: Powdercoating! :-) (patsnitrovette)
I preheat the oven to 400-450. When I put the part in, you can see it start to look wet. When it flows (looks clompletely wet everywhere), I turn the oven down to 350 and let it bake about 20 min.
The peices I've done so far are pretty thin so it flows in about 2-3 minutes. I'm going to do my halfshafts and I think they'll take longer to heat up.

Nice results! I've been using the Eastwood kit for a few years now and am more than impressed with the resulting finish. One thing I found that made a huge impact on the overall quality of the finished part was the powder used. The powder that Easwood sells is good, but lower quailty by comparison to other powders out there. I have had great luck with powders from http://www.columbiacoatings.com. Their product is a finer powder, and lays on smoother than the Hotcoat stuff. You can tell the difference even before transfering the part to the oven!

Re: Powdercoating! :-) (Paster)
Thanks Mike, I'll have to check them out. :cheers: I bought my powder from Pendy Powder coatings but I am going to try different powders from different mfg's.
Well, I learned a couple things with the valve cover. :sad:
1. The powder doesn't want to go into the tight corners
2. Don't shake the gun or let the powder build up on the tip or a blob of powder might fall on your workpeice.
3. You can't touch up a small area if you make a mistake, you have to blow off the whole peice and start again.
4. If the air pressure is too high, the powder doesn't seem to get enough of a charge.
I might blast it and redo it, but it's ok if you use the three foot rule.

Re: Powdercoating! :-) (six-T-six)
My son runs a powder coat department so I have an in for powder coating and most of my parts he double powder coats. Runs them through once, then while still hot resprays them and sends them through a second time.

Re: Powdercoating! :-) (patsnitrovette)
So if you dont like the way they came out,you can reshoot them and bake them again so itll be thicker too right?
Yes my son often runs my stuff through twice to increase the thickness. He sprays them while still hot the second time and sends them back through

I have a son that takes good care of me.
This is a picture of his powdercoating. I have front and rear coil overs. This is the lower A arm double powdercoated.

Re: Powdercoating! :-) (Cmacsvette)
Hey Craig, your tips were really helpful. I still need to extend my oven for my larger peices, but I'm going to try to do something similar to your oven.:cheers: Another visit to Home Depot. ;)
Joe, I really don't have the room for the oven. It's tight in the garage! Maybe I'll put wheels on it we can rotate it around to forum members who need to use it. I'll send the idea to Monster Garage :lol:

1. "The powder doesn't want to go into the tight corners"
What I found works good for that, is to tilt your gun at a different angles. You want the powder to diffuse from the diffuser at the end of the gun at a different angle. Something else I've noticed that works is to move on to another part if you are doing more than one part on the rack, or wait about a minute and go back to that first part.

Re: Powdercoating! :-) (Cmacsvette)
Yep Criag, hitting it at different angles seems to help. :thumbs: The gun I have has some different tips also which I'm going to try. It might make it worse, however, if the powder has more charge imparted to it.
Solid327, unfortunately my gun doesn't have a control for the amount of charge. But I'm not complaining for $80 bucks it does pretty well. :)
