I personally use Billberry and iron x.
Valet Pro Dragons Breath or Bilt Hamber Auto Wheels. Both great, no agitation required - just spray on, dwell (watch the deep red colour change) and rinse off. Bilt Hamber smells a bit better than Dragons Breath.
VP Bilberry isn't a patch on either of these IME.
dragons breath and bilt hamber are similar to iron x more like a fallout remover so they require little if any agitation thats why it will appear they are more reactive than bilberry
dragons breath stinks near as bad as iron x, need to be careful with bilt hamber as think i read somewhere it strips any wax/sealant off
Seal wheels with a good wheel sealant. I find Poorboys to be very very good. Easily 6 months protection and stands up well to everything I've put it through.
