Original finish - is it polished or plated? Each finish will require specific pre-cleaning. Paint to be applied? If it is a `show only/trailer queen' you can use ALMOST anything that has the appropriate color. However if it is a road car an epoxy or a urethane base paint is called for. Many polished alloy wheel come with a urethane clearcoat. The manufacturer of the wheel would be the place to start. The typical spray cans have either a laquer or an enamel base. Ask your local autobody repair shop. The ideal finish would be `Powder Coating' but that could be very expensive.

I've done several sets using Hammerite Smoothrite aerosols, went very well and they've retained the finish well too.

hi,
yes I mean alloy wheels, for racing use. The wheels at the moment are looking a bit scruffy because the original laquer (or whatever it is) is waring off in places. |

I sprayed mine with a good quality 'Wheels' silver paint and they have stood up for a couple os seasons but are starting to chip in places now. Before I sprayed them however I did have them powder coated direct to the alloy so that would have given it a good base colour. That also lasted better but I got fed up with the colour (bright yellow!).

powder coating sounds expensive, can you remember how much it was ?
I'm going to keep it cheap because the wheels aren't that good anyway. |

They'll look awful unless you spend days on preparation. Why don't you get one of the refurbers to do them for you? Pristine Wheels charge about £40 a wheel and they'll look like new. |

Yes these were originally done by a refub man, they shot blast them and powdercoat them, I got Chalk farm Tyres to do mine but it was years ago and the owners were friends of mine but I believe they still offer the service. I wish they would not lacquer them in the first place. if they left them bare you could polish them up. You could maybe try Nitromoors on the laquer and then buff them up.

Hi, I personaly would stay away from powder coating ,the reason being that it does tend to build rather high,meaning that you then have to remove the coating from the Wheel nut landings,that then negates the coating. As Jim says, use smoothrite silver,preferably after sandblasting and applying a good etch primer,then spaying to colour. You should find this treatment will last for quite some time. Incidently the cost of powder coating four wheels would be in the region of 150-200 pounds.

Many moons ago I had a Mk1 Escort Mexico with RS alloys - the 'classic' four-spoke type. The lacquer on them was peeling, with corrosion creeping in under the places it had peeled, so I spent a happy few weekends, two days per wheel, cleaning the lacquer off, polishing the shiny bits & painting the non-shiny bits with Hammerite. Looked great, but then tyres started losing pressure! You guessed it - porous wheels! The solution was to take each tyre off in turn, clean up the inside surface of the wheel & paint it; lucky I had five alloys......no 'space savers' back then! |

I just painted our current set. Gold centre and silver rims - very bling! Although it was to match what TWR did originally. I used cheap paint from (whisper it) Halfords. They looked alright. 8/10. I figured that was good enough. The wheels are treated right, but are prone to little damage. They are working wheels. A year or so later they are probably 7/10, but still look good from trackside.
As with all painting (and as said above) the trick is to start wuth a well prepared surface. |

I don't think you can beat powder coating...but I would say that...I do it for a living!
