Should be the same IMO, but having read so many comments about dull wheels, I feel that the original finish is like an effect paint, which as stated on your other link is very watery and almost translucent, and goes over a black basecoat, that maybe where the fade comes in. but in stating that these wheels had a grey primer not black, and were very dull, which leads me to the lacquer treatment.
On the wheels I repaired there was nothing wrong with the original lacquer, but having searched for another ED30 for some weeks to get a colour idea, the wheels were very dull.
The system I use, is identical to the bodywork finish, ie primer, waterbase paint and hard clearcoat, so I do not expect any fade....the only thing I do not guarantee against is kerbing damage!
