The optical quality of the 135mm/f3.5 is very
good -- comparable to the 105mm/f2.5 from the
same era.
I haven't used the f2.8, but the books I've read
say that it's performance wide open isn't very
good.

To do it right would cost more than the lens is
worth, but If you just want it black, you can
just tape of the rest of the lens, scuff the old
paint with fine steel wool (so the new paint will
stick) and spray it yourself.
Some previous owner did that to my old 135mm/f3.5.
It looks really bad, but it's black.
