Good job bro
I am another babe-in-the-woods pen turner and I have quickly learned that sanding is everything !
i go to 600 initially using DNA between grits . I can start at 220 since I've learned to handle the skew

MM to 12000 , stopping to sand lengthwise after every grit and DNA
I have used the mylands friction polish, I've used lacquer ( rattle can Deft ) and i have tried CA ( tough to master

)
With the lacquer and CA I also MM the finish ....getting better at that
woodturningz.com is where I have been getting my kits and they sell a Mylands sample kit which is 1 oz of the sealer, 1 oz of the friction polish and a small piece of the wax ....I don't really care for the wax

could be I just don't know how to use it
good chance to experiment without spending a lot of money

I am already sold on the Mylans cellulose sanding sealer ....that is
great stuff
I also practice finishing on scraps and off cuts . No need for a mandrel, just chuck it between centers, turn it down to a pen size and practice finishing
Go ahead and pad your butt .....you're gonna slide faster and faster now and you will never again look at small pieces of wood the same way
pS ; I've also learned how to turn the wood off and reuse the tubes when I screw it up ( which is often

)
