After reading and been informed by many about Zaino, I purchased the product , have not yet applied. However, it is really stressed that to obtain the maximum results, must follow the entire procedure which includes multiple different Zaino products.
Always mentioned is the use of Dawn dishwashing detergent to remove the waxes previously applied and the Zaino Clay Bar depending upon the condition of the paint surface.
One of the distributors brochures mentions Guru Reports, which I never heard of, to quote " In a 2002 independent test by Guru Reports, Zaino beat all 45 other waxes and polishes tested as the #1 polish product available.
