I used a microfiber cloth to apply--that is a great photo of the Adventurer that shows the difference the Red Max makes. Your graphics are the same colors as mine--did they bleed too?
I also did 4 coats and no buffing. By the time I finished a side it was dry enough to go back and apply another coat. Dried almost instantly out here with our warm dry air and did not streak. Needs to be applied in the shade and squeeze the liquid out of the applicator to minimize the drips. I tried scrubbing one drip out with the white scrubbie and recoating and it worked OK, but I could still see the drip. It was almost impossible to get off of the hood where I dripped it, so I would recommend covering that when waxing the underside of the cab.
The Bar Keeper's Friend does not have bleach in it so it may not help with yellowing, but it is only $2 for a can so not a big investment to try. Let us know if it works.
Everything is available at Lowes for this job, I tried the dollar store first but they didn't have the Bar Keepers Friend. The gloves I got there leaked and my hands are currently peeling wax. I also bought a new light-colored microfiber cloth there. The wax will transfer the dye from a new cloth that has not had the color washed out so I used the gray and didn't have a problem.
I'd like to see more photos of shiny RVs!
