I purchased a kit from furniture clinic, added a filter to connect to an air compressor rather then using the can of propellant in the picture. The kit came with the air brush. Also added there Rolls Royce red self seal colourant for the stripe. Rubbed it down but removed the steering wheel and picked up a cheap 2nd mk4 golf steering wheel that was knackered to swap with. Then refurbed the mk4 one after all was done and made some money back.
Only thing i didnt do when doing the steering wheel was the red stiching, I masked it up and then blended the colourant close to it and then sealed it all in with the sealer. Used a thin modeling paint brush to apply the paint for the stripe.
I've since lost all the photos of the work I did but have attached the result on the mk4 wheel bottom part to the finish.
