That's not ND filters, that's polarising filters.
An ND (neutral density) filter just stops some light coming into the camera, so you can use longer shutter speeds or bigger apertures vs without one.
A polarising filter (you want a circular adjustable one) reduces reflections and/or glare. And sometimes blackens out speedos.![]()
I'll give it a go, may get lucky and find it works with these too.
