Sorry cant remember from where I read about they clay. But I somehow remember reading from somewhere that u still need to use clay type 1 to remove tar spots. However this is very seldom maybe 1-2 times a year.

You can get ONR from KC's frm lowyat.net, read his blog http://thedetailers.blogspot.com.

I've used ONR for quick detailing and wash. For a newbie like me I can say that its a good way to wash ur car since u dont use much water therefore saving the mama earth. You should get alot of microfibers for this else ull end up inducing swirl marks which can be really irritating. Can get some from bro MSK frm lowyat.net.

I wonder if you've done the sierra glow can u go the sideroad car wash? from what ive observe, the roadside car wash not using proper towel which in the end ur car will have alottttt of swirl marks.
