Loose pinblock

[BILL &PAT HOPKINS]

I tuned a piano recently that had loose tuning pins. In the upper treble I
noticed someone had "banged" the tuning pins further into the pinblock.
Should the same be done to the remainder of the piano.  This piano has
sentimental value to the customer and are willing to try anything.
I also tried to set a few bass tuning pins into the pinblock.  They went in
awfully easy.  Is pin dope an option?
Would it be beneficial to just trying setting the pins deeper into the
pinblock and then dope it up?  Any suggestions would be helpful.  Thanks
