Thanks for all the advise. My motorhome is aluminum if that makes any difference.
Read the labels. Don't know if the marine wax intended for fiberglass works on aluminium. Ok if painted I guess. If bare, have a look in an aircraft supply site. See what they are using.
I have used fiberglass products on stainless steel on my boats. Seems to work well. Used Woodys Wax on my aluminium tower. Dissolves corrosion spots & leaves a hard protective shine.
