I would agree guys that Red Rovers post does sound like an infomercial, but I have got to agree 100% with his post. I used to work @ a Honda Dealership when I was in HS & washed & waxed a LOT of cars with a TON of products (whatever was on sale mostly). while I was in college I worked @ a parts place & used just about every product there too. I just bought the Zaino stuff about 6 months ago & it is w/o a doubt the best stuff Ive used. Bob
