hi Peter. I have no experience with SCTs, but suggest that reflective tape would possibly help a metal tube one as follows:
1. the tube would not cool as much as a painted one, so the mirror could reach the internal air temp quicker,
2. the tube/glass would all stay warmer, so dew problems would be reduced (probably by a fair bit).
if you wanted to try it out, wrap one in alfoil
regards Ray
