All the hard work is the prep work. There are many acrylic finishes (like Red Max Pro, but with UV inhibitors) marketed for the fiberglass boat market - Vertglas from Lovett Marine, Poli Glow, NewGlass2, Star brite Glass Cote, Klasse High Gloss Sealant Glaze, Higley FiberGloss Restorer, and Presto Gelcoat Rejuvenator. They all cost more than RMP, but at least in theory, should not yellow so fast, but eventually, probably will deteriorate and yellow. Decals aren't the best base for acrylic finishes as adherence is not good, and that is what cause the cloudy look.
