I ordered my first Klasse AIO and SG kit about a month ago and I am just amazed with the results. I have never used a product so good in my life. The question I have now....is the rest of my wax collection useless? I still have plenty of MOTHERS CARNUBA and MEGUIARS GOLD CLASS WAX left. Is it bad to put these products on after I have used the AIO and SG? Is there any benefit to doing so?
