I just hand waxed my 2001 Contessa with Shurhold pro polish wax. I bought a gallon thru Amazon portal on BAC for a total of $107 with shipping costs.
This is the best wax I have ever used. No fillers to create the white powder mess. Label says its great for Boats, Rv's, auto's.
It applied easily, and also wiped off easily leaving a super shine. I also resealed the roof seams after I washed it and did all the windows inside and out with an aerosol can of invisible glass(this is a great and easy window cleaner, no streaks and it removes all the window grime.
Just an info post.......
