The Adams wax will adhere fine over top of it. If you do not keep putting coats of wax over it it will most likely be gone in 6 months or so. My mom would not listen to me when she bought her Tribeca. I told her the paint protection from the dealer was probably over priced. After she got it home I convinced her to let me strip the dealer installed protection off of half of her hood and put on a coat of americana. Her car sits inside most of the time. I then left her car alone for about three months until one day she asked me after having her car parked at the grocery store in the rain why half her hood had beads of water and the rest did not. I told her that was where I applied the americana. After that she had me strip her whole car and go with a coat of Machine Super Wax. I do this every June or so and her car still beads and looks good the following June. Also her car stays inside and only sees about 10,000 miles a year mostly on nice days. I am not saying you would have the same results but a coat over the simoneze every few months or will keep a good layer of protection on there. I can tell you the clearcoat on her last two Subaru's was very easy to polish out.
