I can make this job with this highly sponge screwed name suggest in any way, because the sponge after a few applications on the tire (... and for that he has been so well thought and designed ultimately) dissolves more and more, while small spongy "confetti balls" leaves. The chic design moves in it for me completely in the background. I think that since every "perfectly ordinary" household sponge equivalent of a few cents - perhaps even better suited. I try it out at the earliest opportunity and regret this purchase!
