I recently bought a new car and am going to put a sealant on it in the meantime till I have time in a couple months to fully prep it for a coating during some vacation time. I was going to Iron-x, "clay" mitt and then put sealant on. I have read PNS can be applied on top of other products or directly to surface but is there a preference? I was either going to put wolfgang dgps directly on the paint and coat the PNS on top of the dgps or just apply the PNS without the dgps. Will maintain with BSD till I coat the car. Since both dgps and pns are sealants will it be a waste of time and product to use both and be better to just use one or the other?
