Going off the Ron Newman guide that m_c sent be lists this;
  1. Polish part using fine sand paper for shiny finish, or wire wool for matte (can also etch for a little longer for matte finish/hide imperfections)
  2. Cleaner @ 140F 5 mins
  3. Rinse (de-ionized water)
  4. Etch in Lye for 10-30 seconds @ room temp
  5. Rinse (de-ionized water)
  6. Desmut @ room temp 1-3mins
  7. Rinse (de-ionized water)
  8. Anodize at room temp based off 720 rule
  9. Rinse (de-ionized water)
  10. Dye @ 140F for 15s-15m
  11. Rinse (de-ionized water)
  12. Seal @ 180F
  13. Rinse (de-ionized water)
  14. Hang to dry for 24 hours


Other guides I have seen do mostly the same procedure, though one suggested using "Sodium Bisulfate/Sodium Hydrogen Sulfate" instead of Sulfuric which I guess is safer?

As for heating the buckets, I like the one you linked, but I am limited on power in my current workshop. Wont be in my new one till end of November.
Pretty much can't draw more than 3000w in total.

Thinking of getting a couple 12v ones that I can then use one of these cheap controller boxes with. Safer too as those immersion ones don't always have earth on the metal case.

If you have a mains thermostat just tape the probe to the outside of the bucket accuracy will be good enough.

I use these

daily very reliable never had one fail over 5 years.
