Get yourself a USB Microscope
I Spent $77 on a birthday gift for myself of a USB Microscope (Mine is made by Pluggable but do your own research)
I got it so i could look at my bargain bin find First Pressing 1979 Blue Wave Records pressing of "Uncut" by the powder blues which had a locked groove in the middle of "Buzzard Luck"
I was able to use the microscope to find where the offending scratch was and with some light prodding massage the grooves back into shape with a sewing pin.
I don't reccommend doing this on records you can't afford to re hunt down or that you really care about but in my case I turned a locked groove into a minor pop and now have an album that plays all the way through.
The special part about this pressing is it has 10 tracks on it "Gimme Some Lovin'" which is track 5 on side 2 is Omitted from all future pressings both on Blue Wave and on RCA
I have the RCA version so really I on'ly had to care that "Gimme Some Lovin'" played properly on here which it did. I still wanted to see if I could fix it.
The microscope has now fixed for me several minor skips and one more locked groove in some bargain bin stuff I have. The only time I gave up is my 45 of "Had A Dream (Sleeping with the Enemy)" by Rodger hodgson which has a locked groove I just can't seem to fix and sounds horrible otherwise and since its super common and I also own the album it comes from I'm just going to buy the next copy of it I see in the wild and replace the one I have.
