I recommend Poli-Glo.........used it on a 20 year old sailboat and 14 year old Casita trailer. Prep work is .......work.....but it lasts along time and brings back the shine. Lots of happy users, and I'd stay away from floor wax as it's not formulated for UV sun exposure.
You will need warm temps for this work. As in painting, preparation work drives the finished look.
Research thoroughly whatever you do, before you do it.
