Optimum doesn't test compability with other products but what we weekend-warriors have found out is that ONR doesn't affect the bonding of other brand sealants or waxes. I'm not saying there couldn't be issues but haven't heard or had issues. We treat ONR like a product that "doesn't leave anything behind" even if there technically could be some polymers left behind but if I've understood that right, the polymers haven't got the power to interfere.
Hmm, I usually always wash the car after claying with a claybar, if that is what you used (clay)? I'm worried that there could be some leftovers from the clay but as I have always washed afterwards, I can't tell.
