Just a quick topic to find out what everyone's favorite QD is? For the last few years I have had tons of them. ONR in the QD ratio is quite good. PB, CG, NXT, AW, they are all good and serve their purpose. For me, the last two years, it has been z-8. I liked the way the surface looked afterward. That all ended yesterday. I had never used HGAS until yesterday. Menzerna's QD blew me away. It feels as though you just coated your car with FMJ. I am absolutely thrilled. Thank you local store for carrying this making it virtually OTC for us in Tampa. (properautocare is right up the road). Z-8 will still be in my arsenal, as I think it is a fine product, but not like this. The look is far superior. (subjective and IMHO). What are your guys favorite QD?
