I e-mailed Dulon about the need to claybar and about comparing their product to Crystal Guard and Zaino and they replied with this:

"Thanks for your interest in Dulon. No you do not have to Claybar your car. The Pre-Dulon is more than sufficient. It removes any old waxes and anything else that may be on your car. There are no comparisons to the other products that you mentioned. We are a polymer based product with no petroleum distillates or any waxes in it. This product is 100% bio-degradable and more importantly, you only have to polish your vehicle once a year.

We would consider group buys depending on the amounts."


anybody have any experience with Dulon. I have heard good things, but nobody on this forum has posted anything yet. Interest in a group buy?
