They are OEM Porsche parts that are disassembled and painted. All parts are taken apart to do the job. Quite labour intensive but still easier then full leather.

 

To do leather and make it work flawlessly is a lot of work. My friend is doing it for high quality builds but it takes one full week to do one full vent. Because all is sanded and the hole of the wheel is enlarged to make it work. On top the leather is skived very thin. A true craftsmanship!

 

Nice leather work. The factory offered this as an option and the 993TTS all had these parts covered in leather standard.

I would expect for the money they would be leaether but the ones I saw appeared to be painted. I agree with Scott on the SEM products I use them all the time on plastic. Very thin coats, flashes off quickly and is quite durable. Just don't use a solvent on it.

 

I used spray dye for some sun visors from my late 60's Ford. They were a horrid, horrid dirty 'putty' colour originally. I wanted black to match my retrimmed leather interior:


Dirty

Shhhh... don't tell my wife I clean car parts in the sink....

Vinyl/leather spray dye

Much nicer!

So you can get a good finish using relatively cheap products with a bit of effort. I've no doubt Singer are using something more expensive that what was in that spray can.
