I am sure others here have additional TIPS.
I chose Isopropyl Alcohol as a evaporative lubricant and machined a brass "driver" to Set the fasteners w/o tearing them apart. It contacts the tip and flange of the fastener boot at the same time and prevents the tearing from a blunt driver.
The flat Pad I used to have used a stiff plastic fasteners that was hard & ridged and did not replicate the originals to my satisfaction so I sourced the ones show based on recommendations from of others here.
I hope y0ou find this helpful,

That's a great tool Jim as I punctured one of those rascals but had spares luckily. I used some of my faithful lubricant Dawn Detergent to put plugs in and then a gentile wipe on the firewall side and bingo. I bet you could rent that tool out to people. LOL
