Can clear coat cover low spots?

How important is it to completely even out the part when sanding? I have a stubborn part that has a hard time leveling out, and after multiple sands and epoxy layers, it's not sticking well and letting me sand it level. Will adding clear coat cover this? or will it show through?

You can see some of the low spots in this picture:

I've had things like this in the past.  They do fill with lacquer and it looks OK but you do get a ripple in certain lights.  If you ladle on the laquer and then flat it back you can get it properly smooth.  I go down to about 360 and then recoat the lacquer.  Anything smoother than 360 is wasting your time IMO.
