My suggestion would be a thorough cleaning then two coats of Walbernize. Walbernize is a product made specifically for Airstream's Plasticoat and provide the protection needed. Typically, the recommendation is to Walbernize twice each year -- it has helped keep the six year old Plasticoat on my Overlander in good condition (I do have some damaged Plasticoat on the domes, but it has been limited through applications of Walbernize). You can find Walbernize
from a number of online sources.
Automotive clear coat products probably would not be of great help as they aren't designed for the type of expansion and contraction that takes place with our aluminum bodied coaches -- and they are also designed to be applied over paint rather than raw aluminum.
Good luck with your caoch!
