DIY Powder coating

I think i going to try powder coating my own parts and see where this leads.
iv been doing a little research on the diy powder coating guns on the market after seeing a small clip on the tube about it the other day.
it seems to be a fairly inexpensive venture to get into and might be fun to and who knows i might even make a few bucks as well once i get it right.
now theres only a few guns on the market right now and only one stands out and the rest seem to be complete garbage.
the one i have chosen is the Eastwood Hotcoat Powder Coating Gun.
now the gun from what i have read has had good reviews and they seem to have every powder known to man including 1000 degree high temp
the others not good the Craftsman and the WAI Do-It-Yourself Powder Coating Guns are both made by the same manufacture and seem to do nothing but break or come pre-broken right out of the package sorry thats not for me.
so other than the gun the powders and a few other items that i already have and my wifes brand new oven i think I'm good to go.
just kidding about the oven i wouldn't do that to her she would castrate me for that and i like my junk right where it is lol.
i should be able to pick up a used electric oven at a resale shop somewhere for next to nothing.
who knows Christmas is coming maybe Santa will bring me what i want this year and if he don't I'm going to shove a potato up Rudolf's tail pipe lol

What would you be powder coating? There was a brief article in Cycle World not too long ago about the pros and cons of powder coat as opposed to plain ol' paint.

Paraphrased, this is what it said.

Pros- It is VERY durable as opposed to paint. The motorcycle guys have their lower fork tubes pc'd for this reason.Generally, it is applied in thicker coats than paint which can help imperfections in the base metal.

Cons- The big one is color. It is a lot harder to obtain the same kind of shine with pc than with paint. This is because of the fairly large particle size of pc. The best finish is achieved with a thick coat, which might not be suitable for components that have to fit together snugly, or have to flex ever so slightly. If you use a thinner coat, it tends to have the orange-peel finish. To get the smoothest finish, the person must watch the process very carefully, and even then it most likely won't be as shiny as paint is. Obviously, you also have the heat issue which is in the neighborhood of 400 degrees. (So I guess that means I'll have to wait for my powder coated PCM lol)

If your doing suspension parts or stuff like that, I would say go ahead. But if your doing your hood or other body work, I would say no way.

I think if someone powder coated there body panels i would laugh at them till they punched me in the head.

I was just on Eastwood's web sight again and seems they even have a clear coat.
and the customer pics look pretty good to me so i guess i will just have practice with it till i get good at it.

P.S. when i start to put out a good quality product you can send me your PCM and ill see what i can do lol.

Couldn't the PCM case be gutted of all sensitive stuff, and then powder coat it and put it back together? I'm not familiar with how these are put together, just throwing it out there...

As for body pannels.... A friend of mine was building a 1923 T-bucket... fiberglass body and pickup box, but was going to powder coat the frame... actually got to the point where he found an oven big enough to hold the frame, but it was too long a drive, and he traded the 'bucket in on a Pontiac Chieftain... I think that a powder coated frame would have been great... but yea, body pannels... that's getting a tad excessive and over zelious.

Thank you for the paraphrase of pros and cons.

Someone mentioned suspension pieces. Make sure you don't pc any springs or anything that is heat treated. Once you put it in the oven to cure, the added heat will ruin coil springs and leaf springs. If you did leaf springs they would have to be taken apart cause they have slider material between each leaf, but then again, the heat would ruin the heat treat and the springs would sag and fail.

In the motorcycle community, if your doing a restoration, or a custom bike or something, pretty much you are the talk of the town if your frame isn't powder coated.

I was just joking on the PCM comment lol.

I never thought about the heat messing with the temper of the springs. I don't think 400* is going to do that much to it though. (Just my gut feeling.) However, I wouldn't put a strut or shock in there lol.

I've powder coated a few things before. Just can't spray and bake. Not to mention you don't want to use your home oven, last thing you need is say a pizza or a turkey coming out tasting like crap from the powdercoat fumes.

Nor would i anything that cant stand 400 degrees for 20 min cant be done.
and yes i agree with you on the point that some metal parts not all will lose there integrity at that temp in 20 min.
as for springs I'm torn on that one after all my research on this subject i still see that its been done on allot of different sites and have seen them before and after now how much spring strength is left i will have to find out im curious.

Well apparently you can do springs as long as the temp stays under 350 degrees the spring will be fine the only difference is the curing time.
so i guess thats good to know should someone want them done.
i still think my idea of using the spray on plasti-dip would be allot better for flexibility and rust prevention and it comes in five different colors white yellow red blue black and clear.
