B/W Negative Scan Scratch Removal

[ZuikosHexanonsandVivitars]

Slides or color negatives are easy. My scanner can do IR simultaneously with the scan in visible light, thus the Silverfast software can remove reliably any other blotch or scratch within a few seconds, and my results are neat and clean. The software in its latest version even learned to deal with Kodachrome slides. However, it´s still impossible to scan black and white negatives with the IR feature, since it cannot penetrate the silver halogenide layer in those films - thus all my B/W raws are scratched, and sometimes that badly that manual PP would take hours for a single image.

Next, find a software that manages B/W scratch removal? So far I failed. Even the famous Polaroid PolaDSR does a crappy job with B/W.

Is here anyone who tackled the problem and can give me advice?

If the scratches are on the film base side (i.e. not the emulsion side), as painful as it is, could oil-mounting like they used to do in traditional photomultiplier drum-scanning help mask the scratches?
