Wash and protect a RV? Help!

So after searching through the forum I'm still a little lost. I have a 20 foot travel trailer with that ribbed metal siding. I do not have the desire to take this task of cleaning and protecting it with a polisher being as it would likely be exceedingly painstaking due to the shape of the panels. I'm having a hard time finding the right products for a LSP. So here are my questions.

1. Do most use a brush with a flow through water port or one without

2. For a LSP I want to use a spray. Currently are there any spray wax/sealants/coatings that will be just as good as a normal wax if so which one?

3. Thoughts on Hydro2 for this type of job.

4. I plan on using a foam cannon which wash would you choose for this application?

Thank you.

I would recommend Optimum opti-seal. Wipe on walk away is great for large surface areas like rvs. I'm sure hydr02 would work fine but not last as long as opti-seal. As for washing, I prefer ONR (Optimum no rinse) on my travel trailer.

Hydro2 would defiantly work just depends how often you want to apply. Most get around 4 week range with it

Since there is no test kit to see if it’s actually still doing something we are going by beading performance and the ability to sheet water

Sonax Polymer Net Shield (PNS) is probably about the longest lasting spray sealant I know of

I would rinseless wash it using a grout sponge or lake country blue sponge or Optimum big red sponge

The brush on a pole will be much more abrasive and wear your lsp down quicker

Megs Fast Finish would be another easy one to apply and give good durability like the OS. You can get it OTC and probably one of the cheapest at the same time.

I use a Boars hair after soaking for at least 20 minutes for wash and use the cheaper flow through brush with a drying towel draped over it for drying. I wax once a year with Collinite, wash with Optimum No Rinse and Wax and maybe 3 Months or so with Optimum Car Wax. I had a trailer with the ribbed aluminum panels and yes it was a pain doing anything but washing. The paint on those panels is also VERY thin.
