Protective film on switchplates
Mea culpa is this has been covered in another thread somewhere.

While drilling some Cooper 304 stainless switch plates I noticed strange burring on the front surface of the plate. This burring turned out to be a very thin clear protective film coating. You can grab a hold of it and carefully peel it off in one whole sheet. It is not present on the inside of the plate...just the outside.

It is applied very smoothly and hard to tell it is even there at first. Has anyone else found this?

its jusy on the one side to keep it from getting scracthed. But you plan on sanding it anyway.

True...just didn't expect to find the film at all. This is first time working with SS electrical covers.

Will be building this generator without sanding the plates and take measurements as a starting point for further experimentation. Next generator will have bead blasted plates...the next sanded.
