I just picked up the following Meguiars products; Hybrid Paint Coating, Hybrid Ceramic Spray Wax and Hybrid Ceramic Detailer. I am debating using them on one of my vehicles for the winter. I know Sonax PNS with a monthly top off with BSD can handle Pennsylvania winters pretty well. I just put the PNS on our other car. Love everything about PNS and BSD except for wipe off of the PNS, and the fact both of them are non slippery to the touch. If the Meguiars trio can get me a year, and add the ease of wipe off and slippery feel, that would be a huge win. I have watched MK's Details & Deep Dives on YouTube. This guy used to work for Meguiars and helped develop all of these products. According to him, HCW and HCD are both great topper for HPC, but will probably not stick to well for the 1st 6 months at least due to HPC pretty much rejecting anything adhering to it. He stated if you wait more than 1 hour to apply a 2nd coat of HPC to itself, it will have started curing enough that it will try to reject itself.
