Q
can you use a pinch lens cap over this filter?
A
The Answer is Yes. You can use a pinch cap over most filters. ALL my lenses have a filter of some sort on them. I use to use a lot of "traditional" lens caps on all my old Nikkor lenses but putting them on and taking them off became a giant PITA, so I got a Pinch Cap as a test. I then converted ALL the lenses to Pinch Caps. Hope this helps. 
Q
I just bought the k&f concept 82mm variable fader nd2-nd32 nd filter and i bought the 82mm lens cap but doesn't fit. what size lens cap fits this?
A
Alternatively, you can buy neoprene slip on lens covers too. I ran I to the same issue when I bought my VNDF and opted for the neoprene covers instead of plastic lens caps. They work great, just a suggestion.
