Acetone smoothing is mainly for FDM prints made from ABS or ASA and works because those plastics are readily soluble in acetone.
For resin prints acetone can be used as a substitute for or additive to IPA when cleaning off excess resin before curing. There’s even some evidence that it works better than IPA alone for this purpose. Although, if you leave a resin print in the acetone too long it can cause some discoloration and make the part more brittle.

No, the reason clear 3d prints are cloudy is because layer lines cause scattering, which makes it appear cloudy. Coating the surface with a clear epoxy fills in the tiny gaps that causes light to scatter, improving the optical clarity.

Whether you’re filling the low spots or melting away the high spots, I think you’re achieving the same result.

Yeah but this whole post is about resin prints, which cannot be acetone smoothed.
