Mahle - Magnesium Gas Burners, Wheel Refurbisher wanted Options

[porschetub]

Exactly, a really good prep job ,etch primer then the right basecoat and clear with a quality product,then you have a real nice job...not really beyond any good paint shop if you aren't DIY.

The factory had some kind of Blue primer as base. Just For Your Info

The way this thread is going, the OP will need to learn how to smelt magnesium, pour some ingots, make molds, melt the ingots and cast the wheels.

I hear that sixnotfour has the recipe for the magnesium, easy peasy.

Sorry for the question, but do these come in both Mag and aluminum ? What about pedrini's ?

These are original 914-6 or 911 wheels. They're made by Mahle, and are magnesium.

There are reproduction ones currently made out of aluminum. They are rather heavier. I'm not sure if they have 914-friendly offsets, as they are generally intended for the Bug market. They are available with several bolt patterns, including "wide five" and "narrow five" as well as four-bolt.

Note that these are not the same as the four-bolt Mahle 914 wheels. The four-bolt Mahles are aluminum, and are a bit heavier than the four-lug Fuchs (when I weighed some). They are four-lug only, and come only in one size and offset, and are intended for 914s.

The Pedrini wheels you refer to are similar to the 914 Mahles but not identical. They are also aluminum and were made for 914s.

Everyone is making this into something a whole lot bigger than what it needs to be, it's just paint. The wheels may be special, but the finish is not.

[porbmw]

understood
It is just paint...
And powdercoating is likely a hazard to the end product....and most assuredly Porsche did not powder coat

BUT
"what"..is the "just paint". Anyone know the color code, etc that Porsche used...

I, for one, would like to know, as I plan on doing my own "someday" (IMG:style_emoticons/default/biggrin.gif)

[raynekat]

I agree with those saying just use auto paint.
No powder coat.
I would never put a magnesium wheel in an oven, period.
Plus if you ever need touch ups in the future, ya going to touch up the powder coat? Normal car paint is easy to body work and touch up.

Just get the correct silver paint and get a good shop to paint and clear it.
Done deal.

Be aware Harvey is in the middle of Fire watch in Oroville, CA..maybe a little hard to get a hold of at the moment..

I think everyone gets that it’s just paint. The point is, it’s not just a wheel...

I am going to need more convincing before I can agree with you (IMG:style_emoticons/default/poke.gif)

All kidding aside - a previous post stated that the primer may be a blue color. So I did some searching and found that there may be a conversion coating or special chemical dip that helps seal the metal so there can be better long term success with paint

I admire your confidence Travis. I agree, you can just paint it. With some skill, you might make it look very good. My point is of course that Harvey would know exactly what that blue primer is and he would use it. If you visit his shop you’ll get a tour and he can show you factory original wheels in original condition. He will then restore yours better than that.
My point is that the value and rarity of the wheel calls for extra care.

Here’s an example of Harvey’s work. Anyone can anodize a wheel. Harvey’s processes include a pretty precise temperature for the anodization tank. He won’t tell the process. These wheels are now about 6 years old and still flawless. That’s tough. I don’t baby them...

How long was the wait for Harvey to do his magic?

[mepstein]

How long was the wait for Harvey to do his magic?

He usually takes a year /-. Like people said, it's just paint but there are times where you want something 100% perfect. For wheels it's Harvey.

Silver. (IMG:style_emoticons/default/biggrin.gif)


I have read somewhere around here that Wurth silver wheel paint is a very good match to the original paint. Don't know how true that is.

That is quicker than what I heard. At one point someone shared that the running backlog was 18+ months a few years back. There are more players who are restoring porsche wheels now with a faster turn around time.

Data point: Back in 2013, I purchased a set of 6x15 flat Fuchs from Harvey. He sourced the wheels, refinished them and put tires on them. It took 8 months. I'm really pleased with the wheels.

[raynekat]

I've heard Harvey is more like 2 years now.

I pray he and all the others in these areas remain safe. As far as the Mahle wheels, I’d be more concerned about their structural integrity than the absolute correct share of silver paint.
