My valve covers are painted all black, including over the Lamborghini lettering. Shouldn't be too difficult to sand back the letters to bare aluminium as you suggest, Raymond.

These covers get pretty hot. What "clear coat" could you recommend that could be applied over the bare metal that would stand up to the temperature?

Reason I ask, is that I would also like to carefully "hand" clear coat the raw aluminium Lamborghini lettering and surface that is beautifully machined on the tops of the plenum chambers. This is a much bigger area. My experience on other cars is that this type of aluminium machining looks fantastic for the first few years but slowly they oxidise and corrode, especially when they get wet when the engine is hot, and then they don't look so "flash".

I have been wondering for sometime what clear coat I could apply to these surfaces, that would stand up to the heat and wouldn't yellow etc. Need to do it while the car is still new and before the surfaces start to oxidise.

Any suggestions?
