Gold paint code for Campy's

I found the best color out of a rattle can was Duplicolor's Engine Enamel Universal Gold, DE 1604. I later had my wheels powder coated, let me know if you want details of that.

That's interesting. I had read this here before and inquired with Central Connecticut Coatings in East Hartford.

They do a lot of work for Cobra Automotive who has done some of the detail work lately on the GT40 Mk IV Hollman "continuation cars".

They say, no. Magnesium cannot be powder coated.

Anything that needs to be coated needs to go in the curing oven at 750 degrees F.

They say that is extremely risky with magnesium. Life threatening risky.

They also said that heavy casting often develop "fish eyes" due to impurities rising out of the casting in the heating process.

I am not posting this to contradict anyone. Just repeating what they told me.

"No way" was the exact quote and it came with that explanation.

Call them. See what they say? (860) 528-8281

Part of the confusion comes from the fact that some powder coatings cure at 350-450F while others cure at much higher temps. The higher the cure temp, the more likely you are to have coating quality problems. But either temp gives one the opportunity to simultaneously anneal the magnesium castings and relieve stresses, since that only takes a minimum of 275F for about 3 hours- low enough to do in your kitchen.

In my kitchen? My wife will stick my head in the over with them.

Give me a name of a reputable shop that does magnesium. I would like to get mine done but I am getting conflicting information.

Oh, the name of someone who doesn't do it at home in his own kitchen?

I want to hear about curing temperature vs. durability also. I don't wan't these things peeling in a couple of years and don't want the risk of them peeling off the coating internally within the tires where I won't know that until too late?

The coating that ECC put on my 180's has seen more than a few wrenches dropped on them and after 4 years are still new looking.

There was some surface rust on these things and who knows what inside as they had been running on the car.

So far (knock on wood...ow, that hurt!) not anything through the coating. Not like Hooker headers that peel in a couple of years.

Powder Pro Powdercoating Inc.
1-508-991-5999 powder coated 6 of my wheels. They came out ok but not great. They outgassed in a few places. I would not use them again.
I then used a guy who powder coats from a shed in a trailer park. He spent a lot of time heating and cooling the wheels to get out the grot that was in the wheels, coated multiple times with a primer sealer and sanded down. Very nice work and a great price.
I don't know why Central Connecticut Coatings coats their wheels at 750 degrees F. Most coatings are done at the regular 375 - 400 range.

bdud, I would be interested in the powder coating and where to purchase the powder of proper gold color of you have it available.

Powder Pro used Tiger Drylac Sahara gold.
I can't find the color Chip used, I think it was Antique Gold. I will have a look around.

It certainly ins't my field but for sure they don't work out of a shed in the back.

I asked if they were coating vintage magnesium wheels like on th GT40's, Cobras, Shelby's and Trans-Am cars.

Maybe I got the temps wrong. I don't know. They just said you don't powder coat magnesium.

Again. Just trying to pass this information on. It sounds like there is a big yellow flag on it to me?

Powder Pro is not out of a shed or the couple of companies I called about powder coating magnesium. Chip actually works for one of those companies and does some as a side line, very nice work. I did not have anyone say they would not powder coat mag. Lots of motorcycle wheels are magnesium and even Eastwood talks about powder coating some magnesium wheel centers, http://www.eastwood.com/powderwheels
I wonder why Central Coatings do not coat magnesium they do say they coat anything that can withstand 450F, I think mag is 950F. Maybe it is just their choice because of the value of some of those wheels.

I don't know? I just called them again now and they are still saying no. I need to speak to one person who can explain this but he is not in today.

It may be that they feel they can't control the results to their satisfaction?


Now, if I am understanding your post correctly (which I may not be) you are NOT recommending Powder Pro?

That puts me back to the guy in the shed at the trailer camp?

It's probably just me, but somehow I do not feel comfortable with that?

I could afford to replace my 8" Campi's if they disappeared but not my 10's.


Is there another shop that someone can recommend for this?

I'm not going to go through with this unless I am 1,000 per cent confident first.

I would be doing them in the shinny silver like they do on headers anyway and considering the replacement cost of the 10's now, maybe that's not really a good idea either?

I could always re-paint the wheels the original color OVER the top of the powder I suppose if it looks like crap though?

I don't know. You can clearly see me swaying back and forth on this?

There's a couple if powder coasters up our way. Larry and George have both had good luck with them. They would have the details

$300 a wheel doesn't do it for me so it is just academic.
