  • Your putting excitement back into the YouTube science videos. Thanks for sharing and I look forward to more to come.

  • I think this is very difficult to protective metal surface. If you coating with clear lack then you lose some shine. Maybe if you glow metal (red-hot) with hydroxi flame then you turn them on rust resistant... But this step must bee before polishing.

  • hey, cool subject!

    i will be watching with interest!

  • yes the temps are rediculous, but I dont care for the mylar film version, I did it, but the concentration point wasnt very good. Small mirrors stuck on with mastic would proly work better.
