does anybody know about some chemicals or some other stuff (except grease) to smooth or fill in scratches on the base side of LF negatives?

Tetenal do a product (available in the UK at least) called "Repolisan" which is intended to fill scratches in B&W and colour negs.

I have not tried it myself however so can not comment on its effectiveness - nose grease being free (and in plentiful supply at this location...).

I use Edwal "No-scratch". It comes in a bottle with a brush.

You can use regular Spotone print retouching dyes with a good sharp brush. If you use too much on the negative then you can spot that out on the print since it'll be a light area now on the print.

Repolisan has the effect of coating the entire negative with a kind of glue. There is a small but noticeable loss of definition and contrast over the whole negative, so it is really only indicated where the damage is widespread. I've used it on a valuable 35mm negative that had a large number of small scratches, and on balance the effect was positive. The scratches don't entirely disappear but they do become very much less obtrusive. You probably need to print a grade harder after using the product.

It's expensive though.

Nose grease!

Works great on base scratches, but do not under ANY circumstances use it on the emulsion side.

It really does work. Use sparingly.
