What kind of voltages and currents are present at the ends of dipoles
assuming 100W of RF and the antenna being close to resonant?

Just wondering,

Maximum current is in the feeding point, thus minimum at the ends - that's
pretty logical, as the current must flow between something of different
potentials. In case of voltage, zero in the middle of antenna, and
consequently max. at both ends. So, avoid touching the radiator at the ends
