Powder coating stock ZL1 - aluminum forged wheels?
My stock ZL1 wheels. I love them. But previous user, obviously didn’t clean them well or didn’t clean them with the right products. Because the paint is severely degraded. I got the tires dismounted. And was planning on dropping them off for powder coating.
But after some research online. I’m seeing aluminum/ especially forged aluminum wheels due to the heat treatment process when made/forged. Re-heating to 400* to bake the powder coating. I’ve read it will weaken the aluminum. Does anyone have opinions on this? |

Some powder coating compounds can be baked at 250'. I would stick to that, and certainly not exceed 300'.

I believe the powder coating process of all local shops are 300-400* but the original anneal process degree is 650* , my powder coater said he's done multiple aluminum, even drag wheels and forged wheels and not had one bring back or failure due to cracks, bends of weakening of wheel due to powder coating. I want to trust him, and I don't really want to paint it again as it did NOT hold up well clearly or previous owner just didn't care for them, which is hard to believe because the paint, body and interior of this car is immaculate.

Well, then go for it. I don't know why you're asking for opinions then.
Just the same, if it were my dime, and what you say is true, have him warranty the integrity of the forged wheels in writing. |

But that's a great idea! He said he backs all his work and statements. I'll see if he'll put his money, where his mouth is. Thanks JB! |

My wheels are PC'd. They've been like that for at least 3+ years (previous owner had them done), and they are holding up just fine for normal street driving.

What I’ve read is the baking process causes artificial aging which leads to embrittlement, but I spoke with my powder coater an he said he’d do whatever I asked, but says doesn’t cause a issue as well. If you think about the wheel manufacture powder coates as well but probably uses a low heat curing powder.

Here are my wheels after powder coating I was concerned about warping but the powder coater assured me it doesn’t get hot enough to warp them. I have ceramic coated the wheels and they are back on the car all good!

Astatenate, how did the powder coating turn out? I've been considering having mine done as well. Got any pics of the finished product?

You can see my radial rear wheel setup and the front wheel is still my factory powder coated wheel! They turned out great! He had to go a diff route on getting the old crappy factory paint off because he didn’t want to pit or ruin the aluminum. So it took him about a whole day longer. But the final product is amazing. Smooth. Glossy. And I ended up ceramic coating them as soon as I got them back before they went on car. And now brake dust and dirt washes right off! |
