The sponge, admittedly really an expensive sponge, dissolves in the application with Meguiars Reif Engel quickly and kriselig; tolerate well the irregularities arising from letters, etc. to the carcass, not good. Pity! Blackening effect in connection with the hoop Engel, however 1a, but you could probably also be reached by 50Cent-Aldi sponge or an old rag exactly.
