For those who have tried it, how much more aggressive is it compared to Riccardo yellow? I'm thinking of ordering a 6 pack of it for heavier contaminated cars, and using yellow for everything else.
Its more agressive, but not to the tune of red claymagic. It has more bite and will do for cars that need a bit more bite out a claybar. Just make sure the clay lube is slippery, or it will stick to the paint.
I've used it before and it does have slightly more punch than the yellow but not by much. Meguiars and cm red is much more aggressive.
As mentioned, it is barely any more aggressive than the Yellow. But, not to be redundant, I will add this: I rather use it because it doesn't "stick" to the paint as much as the yellow does and makes claying easier and less of a hassle for me. Lube is important, as with all clays, but I noticed it was less picky of a clay than the yellow.
Sounds exactly what i'm looking for. I find yellow to be more of a fine grade, so blue should speed things up and work for the majority of cars. I do have megs red but designate it for over spray.
