Use tar remover next time !!!!!
Probably need something more abrasive than SRP to sort it.
Using something like a brillo pad is never a good plan, wheels are painted in the same way as your bodywork, you would not rub a brillo pad on that surely !
Wonder wheels and clay should have sorted it.
Hopefully you have just dulled the lacquer and not gone through it, I am sure with some elbow grease you should be ok. Be careful id you try and machine polish them, as I went through the paint on a 182 wheel trying to remove defects.
Just give it a light hand application to prep the surface and remove anything the Menz leaves behind, wont remove anything the Menz has done as it is not filler based.
