These days legacy more means 'outdated' or deprecated as in 'legacy computer equipment'. There are no 'legacy cars', for example. But that does remind me of the crafter's term 'antiquing' for the application of patina and aging effects.Or "legacy" which simply means old.
For the record, I am very, very good at weathering objects. If you need wood or plastic to look like ancient rusted-out metal, I'm your guy. Amateur work as seen in the first post just points to the extreme lower range of quality. Actually, that can't be said. If a client came to me and said "I want this paint job to look like I defended myself against a bear attack with this bass." I just might make it look almost exactly like the first post excepting for the apparent symmetry to the scratch lines. On those terms, that is a successful paint job. On all other terms, it's punk rock hack work -which again will have its advocates.
It all comes down to the eternal verities: beauty is in the eye of the beholder; what is art to some is trash to others (and) there's no accounting for taste. Live and let live.
