well, that's pretty open ended.... I think the answer for most people is "yes" but with a qualifier
Some people use a little steel wool and then move to micro mesh, some use straight micro mesh, others zona paper, others a buffing wheel....
For me personally, I sand the pen with regular sand paper up to 600 with transverse sanding between grits. From there I'll apply Gluboost CA (exact formulation of Gluboost depending on resin vs wood pen), then I use Dr Kirks scratch free, followed by the three Dr Kirks polishes. Craft Supplies sells the Dr Kirks under a different name now and I'm too lazy this morning to go look it up.
I would recommend you check out Mark Dreyer's 10 Minutes to Better Penmaking series on youtube and then go check out how John Underhill (Underhill creations) does his finishing on youtube. They both use a different approach to applying and polishing the CA although related.
I have used CA to seal a pen, sanded it back and then reapplied the CA once everything is level too

I sand up to 600 before applying CA, then I wet sand with 600 grit and then move into wet sanding with micro mesh ranging from 1500-12000. After that I dry the blank and then buff in a plastic polish at higher rpms.
I have Starbound(medium) and friction polish. I will look for some plastic polish. Can autozone plastic scratch polish be useful or is polish not all the same?
We started out with our sanding station being stocked with 180,400,1500. All sand paper cut to strips. I would like to move to Micro Mesh soon. I appreciate your feedback!
Skipping grits, like going from 150 directly to 400 and then directly to 1500 will most likely not give you the results you want.
It will take several eons (if ever) for 400 grit to remove the scratches created by 150 grit. The same holds for jumping straight to 1500 grit from 400 grit.
FYI, I start with either 600 or 800.
This helps a lot! Thank you. My last 2 pens were a result of what you are talking about.
I think the folks that I talk with who turn a lot of pens start sanding at 150/180, 220, 320, 400, 600. Using that 150/180 grit may depend on the blank, sometimes it could be skipped. I know a few people who sand their turnings at the RPM they use for turning, I have gotten in the habit of sanding around 750 ish myself. I'm sure some will say that's too high or too low, it's really what works for you.
Perhaps the most important part is to make sure you sand along the axis of the pen before changing grits so you're not continuing to chase circular sanding marks. It's remarkable the difference that will make. Once it's smooth and perfect, then apply the CA. You probably don't need to sand at 600 again after applying the CA, just go to finishing grits.
I've not used Starbond for a finish, the guys who taught me to make pens all used Gluboost so I just started there and stayed with it because that's what they showed me. I think with any CA the devilish part is finding a way to apply it ripple free. There are probably as many ways there as there are turners on this site.
I have used Flitz polish on pens after micro mesh, I remember looking it up one time and found out it was literally the same polish as one of the big pen polishes just branded differently. I don't remember which one it was. I know automotive polishes can have different grit or "cuts" so you'll want to make sure you're using them in the correct order. The Dr Kirks polish I use is similar to that in the fact that has different grit levels.
I just remembered there are a whole bunch of folks who use the magic juice family of products too. You can check them out.
Post photos of your pens if you'd like also. Plenty of folks on here who will give out pointers, I've certainly learned a lot that way.

Thanks for all of this.
Like I said, we are just getting started. But here is our pens. I tried to take my time with the Hickory/click pen and CA. Everything you stated about grit sequences shows the scratches on my finish. The walnut and african blackwood are friction polish. This thread helps a ton.
Will be watching this in a few with my son. He is 9 and just as addicted to this as I am. Thank you.

First thing is to not apply CA too thickly. Light coats and let each coat dry completely. I apply at around 250 rpm (that is as slow as my lathe will go ) and I leave the lathe running while the CA is drying.
I tend to apply 6 to 7 coats of thin and then 3 to 4 coats of medium.
- On the Soapbox -
I do not like using accelerator as somewhere in the process it boils/bubbles or causes white spots. Others will say they never have a problem with it but I just eliminate the chance all together. I am not a production turner so time is not really a problem for me.
- Off the soapbox -
Once all the coats are complete and dry I then go directly to the micromesh. The coarsest one will definitely be coarse enough to smooth the blank (If your coating IS rough then go ahead and use some 400 or 600 lightly to remove the rough). I will sand with the lathe turning (somewhere between 250 - 400 rpm) and then I will stop the lather and "sand" along the length of the blank once or twice around the entire circumference. I remove all the dust from sanding before moving onto the next grit (I worked in an inspection department and acquired a microscope that I use to see if each mesh has remove all the scratches left by the previous. Not necessary but nice to have). By the time you get to the third or fourth grit you should start to see some matted sheen. Just keep going and by the time you get to the 3rd or 2nd grit from the end you will see a glassy finish appear.
I dont generally wet sand a wood blank but will occasionally wet sand a plastic blank.
I use these micro mesh pads.
One other thing. If you sand the corners of the blank so they have a very slight radius/break to the edge it will improve the look of the finished pen and when someone picks the pen up and holds it they will not be able to easily discern the difference between the where the blank ends and hardware begins
One other thing, I have my micro mesh pads 'numbered' so I keep them in order. I have them in a smallish container and when I'm done each grit I return to the opposite side of the container and then I know which one is next and which one(s) I've used.

Looks like you are from the Midwest. In April you and your son should come out to The Midwest Penturners Gathering (midwestpenturnersgathering.com). We get about 300 penturners of all ages for two full days of classes and demos. It's always a blast. Feel free to PM me for any questions).
