I have never got any feed back on that hole sizer in the install kit, but I use it so often, I included it for that reason alone.
On those pop bumper lugs (I call the nail-screws lugs) I replace the fin style with the barbed style, and just like you, I predrill 2 different diameter predrills first.
If you use the fin style I have learned to remove all of the clear in the area, for the fin will cause a crack or split in your clear.
That install kit is perfect for the stock pfs like you are doing. For a production clear peter does a great job! I also like his work, but there is enough clear down that you dont want to thread thru it, or have the threads of a screw pulling up on it.
I thin that glue out so it will wick in to the wood in 2 sec. The antidote is acetone if you spill any.
I love all 3 of the pinbots. I am the odd man out that likes jack bot the most, and bride the least. That doesnt mean I dont love bride, especially the call outs.
Looking forward to see how this one goes. Lots of custom parts that are only on this pf,
