It may be possible to make a flattish print (full frame) and then laboriously retouch it.
Then, photo copy the print onto film. At this stage, your contrast will bump slightly, your retouching should dissappear and you will be able to make multiple prints of your image.
Duratrans is a material that is uniformly opaque and approximately 1/16 or less in thickness...anything of that type should work if it is placed between the condensers and the negative.

I believe there is a bit of confusion going on here! The shinney side of the film is the base side, the dull side is the emulsion. Are yopu making contact prints or enlargments? If you are making an enlargement the emulsion (dull)
side faces down in the carrier. The base side is on top. If the scratches are white as you say they can only be in the base, (Shinney side) not the emulsion side. To apply vasolene I lay the negative on a sheet of glass with the emulsion down. Then with a tiny drop or finger tip I apply it to the center of the negative. With an index card carefully spread the vasolene over and into the scratches and entire negative with the edge of the card. With cross lighting you can see what is covered and what is not. place the negative with the vasolene into the carrier vasolene up. You can use "nose oil" on either side of the negative because it is so thin it won't drip. the same with glycerine you use only a tiny drop and spread it the same way over the negative. You cannot cure a white scratch in a print by putting anything on the emulsion side. If a black mark/spot/pinhole/scratch is found it can only come from the emulsion side side of the negative. A hair or dust particle on the base of the negative also can only print white. Dust/ lint/ or dirt on either side of the negative will print white! To determine base from emulsion simply look at how the film curls, it will always curl towards the emulsion side! I hope this helps, but I am certain there is still a good deal of confusion concerning your post. Charlie........
Any art store has matte acetate in sheets, which will work very well. A ground glass focusing panel from a view camers will work. Cut the side out of a frosted distilled water jug and lay it above the negative in it it's carrier,
it will work. Even a simple sheet of white typeing paper can be used, let your imagination be your guide. Charlie.........

You're right. My fault, completely. Thank you very much for pointing this out. I don't what I was thinking. Simple error. Sorry.

So, is this still curable with the kinds of grease that you have suggested? There are no black marks however to be seen. Also, how should I clean the neg this time before and after putting the grease? I'm afraid that the emulsion near the scratches might flake off if I have to touched it.
You are not listening to what I am saying. The only way you could get a white/gray mark is from the base side. If the negative is scratched on the emulsion side it allows the light to burn through the scratch which creates an exposed black mark on the print. The only way you can get a white/gray area in an enlarged print is for the emulsion to be totally black in that part of the negative. The density of the exposed emulsion prevents the enlargers light from reaching the print paper. There can not be a "scratch" on the emulsion side causing your problem. To clean your negatives of the "grease" use a standard film cleaner and lint free soft tissue...... I use Kim Wipes. I'll say it once more, if the offending marks are white in the print, it can only be something holding back the light from the enlarger. A hair dirt etc. stuck on the emulsion side of the film could do this but not a scratch! Another method to elininate problems with damaged negatives is to sandwich the negative emulsion down in a puddle of glycerine, first wet the entire negative in the glycerine, let it drip a bit then lay it (emulsion down) on a sheet of double polished plate glass that will fit in your enlarger. Cover the negative and wet puddle with another sheet of glass. Expose and make your print then clean up your mess, and a mess it will make, but it might get you a print. This is not a method I have used, because of the mess, also I have never had a negative that it was necessary to do this drastic of an action to. Once more the facts, it is not possible to get white marks in a print from scratches on the emulsion side of an negative. A white mark can be created on either side of the negative by dirt/hair/lint/ finger prints or anything that will create additional density that will hold back the exposure of the print paper. A scratch on the non emulsion or base side will always appear in the print as white/gray. Charlie........ BTW this is one negative that you would might be way ahead to reshoot, or simply move on and chalk this one up as a step in your learning curve. The emulsion should not flake off.
Thank you very much for giving me the instructions and holding your patience throughout this. I have not been in the darkroom since I started this thread a few days ago because I got sick, but hopefully from this weekend, I'll go back in there and do what you've suggested.
Meanwhile, I think I've figured out the problem. Two out of three scraches indeed have something (counld be dust) stuck in their gaps, so that's what's causing the white marks. But they are on the emulsion side. Does it make sense? On the finished prints, at the end of one of the white marks is a really small black spot, that is where a piece of emlusion is missing, right? However, since the black mark is really really tiny so I can let go of it. Then I'll retouch the white marks if the greasing and diffusion methods fail.
The real problem concerning the care for the damaged neg was that the new scratches appeared on the neg after rinsing and washing it. I just could not comprehend what had just happened. So, I launched this thread. I'm still not sure if my neg-only sponge(the special kind from a photo supply store) I used to squeeze off the water caused more damages or not. The sponge was brand-new and I had never had any problem with it before. So, I was overly concerned if the emulsion would flake off.
Anyway thank you again for your advice, and I'll definitely hang this neg and the first test print somewhere visible to learn from it. It's a real shame I ended destroying the neg which is not replaceble, but I'll print the image enyway for my portfolio because it's just an powerful image. I'll live with it and deal with it.

(CW) Yes it does, because what ever is in the crevice is holding back the light thus printing lighter.
Quote: On the finished prints, at the end of one of the white marks is a really small black spot, that is where a piece of emulsion is missing, right?
(CW) Correct, the missing density in the spot where the emulsion is is missing is passing light thus printing darker or black.

(CW) I am of the opinion that regardless of the methods you try at this point the final print will need additional work. Pray that no one orders a 100 copies of this neg and print :-) Good luck!!!! Charlie.......
