Whats good about they're products over others chris ??
basically newer technology, better purer ingredients,more durabilty,ease of use/userbilty,colour,texture,smell, thats the aim anyway when companys bring out new valeting/detailing lines,
as with all products they will work in certain applications better than others, theres alot of factors involved with any new or older products, theyre all good but some serve better than others in certain sitiuations/conditions.
