Theres a company here local that makes product in house that i use . I am an Auto painter i do alot of custom paint work and i use there products. Pm if you want info. Use micro fiber clothes by hand to put on and one to wipe off. I normally use about 2-3 new micro fibers on my trailer thats 19ft. Do it sections at a time and dont do it in the sun. Theres no way to speed uo the process to get it done correct and ensure every spot got waxed. I learned to just enjoy it and take my time. I also wax my windows.
P.S I hand wax my trailer about every 6 months and it feels silky smooth
