Hey Bill,
I've had a couple of prints with this kind of "perforation repair" adhesive, why anyone ever used it is anyones guess. Maybe they were sniffing the glue but, this stuff was terrible for films. There are are several films that I've rescued from this condition using a lot of patience and Film Guard. Once it comes off, it leaves a white residue behind as well so there must be another cleaning of the film with 91% alcohol and then a little more FG if needed.
It really was a poor test on our amateur film preservation skills but, to my observation, many of the films were damaged more by doing this than repaired. Your story is a classic case of what happens when you run a print before putting on your bench rewinds. I've looked into this, and what worked for me is investing in a Dr. Catozzo splicer. This will make a world of difference on all of your films and how they run through the projector.
Before I had one, like you, I used tape splices--one at a time. Then, I started playing around with repairing all of my films once I got the Dr. Catozzo. I ordered many rolls of tape splice, these are usually much smoother running through at the claw/gate than any tape splice. Eventually, I started to try perforation repairs with mixed results. I wasn't putting in splice tape at every point of damage and toward the end of the damage, putting it tape only halfway through the frame. This kind of repair works but, it causes a lot of flicker.
Eventually, I got it and put the splicing tape parallel over the damaged area--"B" wind, leaving only a minimal area where the soundtrack isn't covered. This looks much better through the gate and does exactly what you need it to do through the claw. Finally, you go through the film with the Catozzo and punch in the perforations onto the tape across the area needed. I never cut film unless its a slight trim to make the image pass a little more smoothly, like a burned frame or a jagged edge. Here's a way to try to save more of of your film instead of trimming off the area.
Here's an example that I did in a minute:
