Ref.waxing.
There is a product called RED MAX #3. Buy at Lowes. Clean wax off RV,apply with rag.4 coats. It does not make a differencehow it is applied-- up down, circle, back and forth. First coat looks streaky, but after 3 coats you say not bad,4th coat you say WOW. Decals look new and shiny. It drys like a clear coat.
Apply one coat once a year.
I have an 2004 allegro bay and it looks new.
1 gal.of red max is enough $ 15.00 to 16.00. for my Allegro Bay 37ft.
