being a tech, I see lots of tractors.  I see lots of poorly maintained tractors.  I know this sounds absolutely crazy, but if you put a coat of wax on the painted surfaces, they won't fade.  If you don't, it will fade-and when it does, it turns from orange to a pinkish color, looks like poo.  I'm fortunate enough to have bought a G1900 from a guy who waxed everything on it, and the hood looks awesome as does the rear fender.  Unfortunately the deck didn't get that lovin'.  Something else that I seen a few years back is on the plastic lawn mower hoods (like the T and G 60 series), you can use a wool polishing pad in a cordless drill, and some fine polishing compound, and that faded hood will look absolutely brand spanking new.  Fender too.  Works wonders!  I know...cause I bought about 2 dozen of them in a years' time, cleaned, serviced, repaired, and polished 'em all up, and sold them.  People aren't hesitant to pay more money for 'em if you spend a little time on 'em.
