u/petthedino and /plotzkea here is the best way I could break it down. I tried to keep it simple but still detailed. If you have any questions just let me know!

Background: I have had this putter since I was 8 years old, we bought it from Edwin Watts brand new in Dallas and every member of my family has putted with it at some point in time. I looked into getting it refinished by the Scotty Custom Shop but it was going to run me over $300 to get it done. I figured I would give it a go myself I have absolutely no experience doing any kind of this stuff, this was my first ever attempt

Tools/Materials needed: I had or was able to borrow almost all of these before starting, which helped keep cost down.

• Blowtorch with appropriate fuel
  
  
• Power Sander Anyone who works with soft metal might cringe at the thought of me using a power sander on carbon steel but I had no other choice. The rust was too severe and there were very deep dings/blemished that I had to power sand out. If your putter isn't too bad you could get by with very fine sand paper.
  
  
• Fine and Very Fine Sanding Discs
  
  
• Acetone
  
  
• White Tamiya Acrylic Paint
  
  
• Needle Paint Applicator
  
  
• Motor Oil
  
  
• Metal Bucket (will hold motor oil that will most likely catch on fire)
  
  
• GOOD crucible tongs (no link because I couldn't get good ones, used for moving the extremely hot putter head)
  
  
• Paper Towels, Q-tips, Microfiber Towel
  
  Process
  
  It's important to note my putter had no paint finish. It was oil can so the only paint I really had to remove was the logo's. If your putter is entirely painted you might have to adjust the steps accordingly
  
  

1. Remove the putter head by blow-torching where the shaft, putter connect. I am replacing the grip on my putter so I stuck the grip into the ground and basically used that to hold my putter head anytime I was blow-torching. Once you melt the resin connecting the shaft and head you should be able to just pull it off with an oven mitt.
   
   
2. Sand it down. This is where all of the dings, nicks and imperfections should be removed along with any excess rust. I used fine sanding disc with power sander, then once everything looked smooth I went over it with the very fine disc to get a better shine and leave no visible abrasions. I never used the power sander on the putter face but lightly used very fine sand paper to preserve the milling I wrapped the sand paper around a sponge to ensure even pressure was applied to the face. Here is a picture of what the head looked like after sanding..
   
   
3. After sanding there will be a lot of metal flakes/dust all over the putter. Wipe it down excessively with microfiber then use acetone to remove any paint from the putter. I just dipped a qtip in the acetone and applied it to the logos, then wiped it all off with a paper towel. This was the least exciting night of work because you don't see too much of a change.
   
   
4. At this point your putter will be just a hunk of metal with no paint and no finish. So now the fun starts. I can only say what I did, and it's a fire risk. I hot blued my putter head using a method similar to how gun parts are blued. It's also Scotty Cameron does it. Outside, I stuck my putter grip first into the ground and set the head back into the shaft. I torched my putter everywhere except the face until it turned dark blue with shades of light blue. Once it was the desired color I dunked it into the metal bucket of oil with crappy, rubber, kitchen tongs. The tongs I ordered were too weak to lift the putter head, and my grill tongs were also too flimsy and I was running out of time because gun blueing generally requires immediate oil dunking to ensure the color is what you want. So I freaked and used kitchen tongs to dunk in oil. They had plastic tips for better grip but the grip melted onto the putter head and you can see a little bit in the picture. Once you dunk the oil will begin to boil and maybe catch on fire. I used motor oil because it is designed to not catch on fire but YMMV. Here is the result about 20 mins after torching
   
   
5. Do your best to wipe off all the oil you can from the putter, now it's time to paint the logos. Use the paint bottle to fill in the logos. A little goes a long way here. This was by far the hardest step. I overfilled the logos and had to use acetone on a Q-tip to remove paint from parts of the putter where it shouldnt be. But I would accidentally remove some from the logo then have to fill the logo, but I would accidentally overfill the logo and have to remove...so on in that fashion for about 4-5 hours. It still wasn't perfect, but it was done. I let it sit over night then lightly oiled it again to protect the finish.
   
   My steps were broken up by days. I worked a little after work each day and it made for a good week! If you guys try it and have any questions please message me!
   
   Edit: several edits for clarity.

I haven't had the chance yet. I cut them last summer/fall but until recently has been too cold to work outside. I cut them using a circular saw and a trickle of water so the cut isn't jagged or anything, but I vacillate between dry sanding with my DA orbital and just getting a cheap diamond polisher. If you do YouTube search for "DIY marble countertops" you can find some pretty informative vids. A couple of multi packs like this and this you can get a pretty passable finish with a palm sander. Just be patient and make sure all the scratches are out before you move on to the next grit.
