Has anyone powder coated their original Rally 2 rims? I thought you could not do more than one color when you were powder coating. I wanted to do all 3 colors. Thanks.

When I had them on my car I only powder coated the silver then masked and rattle can painted the Charcoal. Lasted a long time.

Yes, you can powder coat 2 or 3 coats no problem. Use the correct high-heat tape to mask with. Then finish with a clear.

The powder coat place I was going to use said they could not do it anyway. Thanks everyone.

If they don't know how or tell you they can't I'd find a different place to do your powder coating. They don't sound like they really know what their doing.

Thanks rexs73gto, does anyone know a powder coat place in New Jersey that can do the 3 original colors for the rally 2 rims? Thanks.

I don't believe you can powder coat anything but bare metal as the surface has to have an electrostatic charge to adhere the powder. This is why parts are media blasted so as to be free of any finish before powder coating. The powder is melted into a plastic coating by baking, so it seems intuitive you would melt the underlying powder coat finish trying to apply a second coat or color.

I had my 8 lug rims powder coated Satin Black when I restored the wheels.

Then when I took my rims back to the tyre place to get the tyres remounted, they refused to do it on the grounds the tyres may not remain fully sealed against the rims in an adverse situation. Such as panic braking or the car sliding for some reason or other.

I easily found another tyre place to do the job but I've heard that other guys here have also encountered the same resistance to fitting tyres to powder coated rims.

I guess they might have a valid point immediately after the tyres are fitted but I can't see it remaining an issue after the tyres have settled down into the rims and have had some use.

I've powder coated previously powder coated parts a number of times. Sometimes I will do a part and realize after baking that it is a little thin in some areas. Just hook up your equipment and go. No problem getting the new powder to adhere. There is no concern about melting the previous layer. It's already hardened and does not flow again when reheated.

Aha! So the powdercoat is a thermosetting plastic, not a thermo-plastic. Makes sense.

I have powdercoated several sets of Rally 2's. I sandblasted them first and then baked them. The first color I did was the dove grey powder on the backside of wheels. The next was the Argent silver powder on the front side. I then used the masking sets and painters tape and painted in the charcoal center section. Last I covered the entire wheel in clear coat. They look the same after ten years.
