Im sure its alot easier on say, ph2 172 wheels...
I did some f1's and it was a nightmare, just a pain in the arse and the end result wasnt great, the finish isnt very durable and covering the spokes of the f1's is very hard without getting drips etc.
Sanding down the spokes and small areas is hard and extremely tedious.
If you were doing the ph2 172 wheels or some dynamique wheels its probably a total breeze tbh.
I just had my new f1's powdercoated instead of spraying them myself as I cba with the hassle i had before. Even tho it was satisfying. And if time wasnt of the essence and i had maybe a dremel to sand the fiddly bits then I may have been tempted to do it again.
However powdercoating will last longer etc.
Hope that helps?
