Not a problem if you're going to be polishing anyways but depending on the aggressiveness of the clay it could induce marring.
Instead it's a lot better to make your own lubricant with just car wash detergent and water. Mix 1 ounce into a 32 ounce spray bottle of water.
This is a lot more economical as you can really be generous with a simple water/detergent mix which is what'll save your car from marring from underlubricating because you're using an expensive spray wax or detailer and trying to stretch it.
Thanks, never would have thought about that, I have meguires wash and wax.....will use! Only because I threw 2 coats of wax on, I should of polished clay bar.....yada yada.....but didn't have time today, smooth but still feel a lil roughness or particulate in paint, so I want to clay bar....glad i can over wax!
