Powder coating process question.

[TYTILIDIE]

I was in a hardware store the other day and noticed a can/bottle of something and when I looked at the tag it said powder paint. I am assuming this is for powder coating. So I then thought to myself hey, if they sell this crap in this store it must not be that hard to do. I want to do my Z06 wheels in black for the TY and was thinking that maybe ild try to pull it off myself. What goers into it and what all do I need? Any step by step info? Thanks in advance.

i doubt it will be anywhere as good as powder coat, from what i understand powder coat when applied is then heated and thats how you get the nice finish, i cant see that coming out of a spray can... but i could be wrong.

I believe it's heated to about 400 degrees, could be wrong though.

Powder coating is not hard, however it does not come in a spray can either.
It is baked, at approx 450 degrees for normal powders.
I do my powdercoating in a regular kitchen oven with a power vent on it, bake for 20 - 25 minutes.
Coating itself is really easy if you have a clean surface.
Using a kit like this one makes it very simple.

I have powdered all sorts of stuff, from intakes to brackets to BOVs to lacrosse sticks :tup:

Some results

it all depends on how the wife/girlfriend feels about having truck rims in thier ovens......

The powder is easy. The prep is a bitch!. ZERO 0000 ........ oil, grease, finger prints old paint etc.
Baking is then the next thing, if you use a kitchen oven, it has to be spotless also. Even grease / oil vapor will ruin the process. You will be limited to what will fit in the oven unless you wanna drop big dollars on a "commercial" size and I recommend a good glass bead cabinet and a real "solvent washer" not that water base crap. Also the air system must be pretty clean also. If you can blow un-contaminated auto paint with the filters you have now (no fish eye ect.) your prolly ok. Using a compressor and hoses that deliver all most as much compressor oil and or water as it does air ain't gonna cut it.

New powders are out that have cure temps as low as 300 deg. but that will depend on what you are coating and how much heat that part will see also. Low temp powders usualy have a max temp of around 400-425 deg. operating. The Eastwood powders are pretty good for the cost and for general engine parts and frame stuff why pay more?

Renz and I have done some powerder coating in my old kitched oven.. We did it up in my dads pole barn and we didn't bother to clean/vent the oven.. The fumes weren't that bad. Some stuff came out nice and some came out like crap.. I think our problem is that we, ok I, applied way to much powder to some parts.. The ones that had less powder came out quite nice..

Interesting. The stuff I saw wasnt in a spray can. It was a white bottle that was shaped like a flask. Probably about 18-20 oz. I dont think my Z06 wheels will fit so I may have to take them somewhere I guess. Is powder coating usually real expensive to have done on something like that? I may look into it further as Ive always wanted to do it with engine parts etc..

Depends on where you go. it cost me $900 to have my entire frame, bumper supports, spindles and trans cross member done, and that included pickup and delivery at my house via box truck (I can tell you for certian that the amount of powder the frame took cost about $450, and the place is 35 miles from my house ) ... so it's pretty reasonable most times.

It's really not that expensive to have someone do it. If I remember correctly theres a local place thats about 40 bucks a wheel. Don't remember exactly but i'm pretty sure it's around there.

Hey I was reading the post you had up the other day and was going to PM you about some stuff. Are you still doing the whole donation deal? Where in Washington are you at, I'm in Portland just wondering how far away?
