I have one of these from Mark and it still leaves spots on my car so still have to dry it down with a towel.
Leaves horrible tide marks on the 458 front aero wings as it is a concave shape so a small puddle collects there. So if I forget to soak up the water a nice mineral ring remains.
Donít have a particle reader so donít know how well it is working or ever worked. Only had it 2 years I think and itís not used that often so the resin should still be good.
Just my experience.
