Carnuba does from my experience as a detailer.
The fat and alcohol cleans, treats and protects it to an extent.
Not going to last forever but prolongs the life IMO.
Of course mine is non scientific but experienced based.
Exposure is the culprit.
Precisely why I keep mine covered.
My last trailer decals were 14 years old.
Only upper caps weathered due to the constant rubbing of the crappy cover on them.
Sides were in VERY good condition.
