super nuts model. Love it.
But... too many copper nuts/bolts to reflect reality. I understand choice if going for color contrasts, but appart from temp sensors, i never found any bolts in copper/bronze on cars. Must admit: don't know anything about race cars, but i'd be surprised if.

Copper?? I think you mean brass Wim. ;)
You find yellow anodized or nickel plated screws and parts on a lot of Porsche cars, even the older ones had them, to me it looks very realistic.

agree with Guido ! I've double checked this at the RSR exhibited in the Porsche Museum. The bolts have a brass/silver look alike color, which is according to the Museums staff periodically correct. The bolts on my model have been painted with a Alclad Brass/Silver blend to imitade this look

Ah, yes, i know these, but i remember them to have more yellowish/golden/silver/areas mix.
You could buy them per kg, low value & low strength bolts & nuts. Maybe they 're also available 8.8 & up, ok.

great so to see things come together Uli. And thanks for the insight considering Etching all.

The screws and bolts Wim mentioned look to me as passivated(sometimes translated als passivised). It is a similar process to galvanising(grey flocking as a surface finish) but with electric current instead of heat. Also called 'electric galvanising'. The quality and thickness of the steel have an influence on the colour, as well as the current and duration of the exposure to electric current. This whole process leaves a goldish, greenish, purple tone as an almost natural protective layer. Hence the colour differentiation. As far as i know electric galvanised steel can be passivated yellow but also in other colours as a result of the substance in which they are submersed.

The whole process is a relative cheap method to protect/seal steel with a minuscule layer-thickness. Chrome-6 used to be used for this here in the Netherlands, but thats banned because of health issues. downside of electric galvanising is that the quality of the protective layer deteriorates quite quickly in relation to thermal galvanising for example. One of the reasons they where used on temporary structures/objects(?) I think.

Anodizing is a process of activating the surface to transform into a natural protective layer, but as far as i know, only applicable on aluminium/aluminum. Here pretty much al colours known to man can be created, If pockets are deep enough.

Sorry for the text and likely flaws; only have basic knowledge of materials my job requires me to have. Great to see different techniques to mimic or even recreate 1:1 materials.

Hi everyone and thx for your continuous interest !

Jesse, thanks a lot for your detailed explanation of the process on how to passivate/galvanize parts made of steel. I remember when I was a student and working during semester break in a company who run a galvanic operation doing exactly this.

On the RSR project, I could in the meantime install the fuel tank, which is covered by etched parts to replicate the sheet metal of the real car. Likewise, the "cage" is fully assembled and test fittet with the chassis and bodywork. Fit so far is looking good ... no rework required :-)

Test fit of "passenger" seat. The seat is covered with a lady sock :lol: and hand painted with a brush to replicate the GFK texture

Next update will be when I've finished the Dashboard.

Awesome work Uli, the seat looks perfect, color and texture looking great!
It`s coming together slowly, feels like watching a restoration of this car, like that! :)
