We have a number of sticky shutters on some of our Source Four lanterns and we're just wondering what is the best way to fix them? Is there some kind of lubrication that we can put on them or is it a case of opening up the shutter assembly and doing something to that?
Graphite powder can work wonders.
It's about the only thing that can take the heat, also because it's dry any excess that gets onto the lenses will just brushes off.
