Does anyone know what the coating is on the second gen flash to pass lenses?

I`d like to reapply the coating if possible. I have a pair that are not yellowed and are still clear only the outer coating has peeled off most of the surface.

Any ideas??

 

not sure exactly what it is, but you could buy some PLaticoat clear at lowes or home depot. Its a clearcote for most plastics and vinyl. That might work?? obviously I would try it on something else first.
