    Here's some info on the process used to paint a modern F1 car I found interesting.
    500 grams of paint for the whole car!


    Renault R24 project: The raw carbon monocoque has reached the time to be transformed into a true race car, and don the livery of the Renault F1 Team.

    Next week will be an important step for the team, with the chassis departing to be painted. When it returns, it will sport, for the first time, its race colours. As if by magic, the raw carbon fibre chassis will begin wearing its heart on its sleeve.

    A special relationship. The chassis are not painted at Enstone, but 50 kilometres from the factory. A specialist supplier takes charge of this high-precision job. "The monocoque is weighed as it leaves the factory,"
    explains Keith Dunsby, Assistant Composites Manager. "It is then collected, and returns two days later."

    Naturally, painting of the
    chassis occurs in the utmost secrecy. Apart from the five employees who work directly with the team, nobody is allowed access to the car.
    "Furthermore, our partners are prepared to go to every length to ensure the quickest turnaround, to the extent of working through the night,"
    explains Keith.

    Taking measurements. The first chassis will give Jon Woods, the team's Head of Graphics, to fine-tune the car's livery. The engine cover and nose are required in addition to the chassis in order to lay out the full livery. The car's lines are recreated using adhesive tape, with the aim of avoiding lack of continuity between different parts. This stage allows the team to take the measurements which are then used during the rest of the season.

    "Afterwards, our objective is to paint the chassis for the minimum possible weight, firstly with a coat of white primer, then with the final colours," continues Keith. "By the end of the process, the monocoque shouldn't have gained any more than 500 grams extra. We check that carefully when it gets back to the factory, because weight is such a critical parameter in F1." The paint then dries in an over, heated to 60°C. After cooling, the part then undergoes a polishing process several hours long.

    The devil is in the detail. "The finished article must have a perfectly smooth surface at the points where the colour changes," clarifies Keith Dunsby. "The tiniest superfluous millimetre can ruin part of the car's aerodynamic performance." With the seven chassis produced each season, bodywork, wings, developments and the stripping and re-painting of the chassis between races, several hundred paints are painted each year.

    Sometimes, even insignificant components need to lick of paint: parts produced in resin by stereolithography are painted black in order to standardise their appearance. Finally, Keith's nightmare: chippings.
    "Some circuits are harsher than others for the paintwork," he smiles.
    "After taking so much care over the car's appearance, it almost breaks your heart to see all the small stones on the edge of the circuit that chip the paint!"

    Original F1 cars are all black because of the carbon fiber. The paint is only used for the general colors. Ads are actually very thin adhesive stickers.
