Powdercoating is the best way to go for those that want to remove their pedestal. And, for the most part, it's pretty bullet-proof.
I had some paint flake-off near my base some years ago. What I also discovered on my boat was grounding/bonding connections to my aluminum fuel tank & pedestal. The area was small & was able to manually recoat this.
Now comes into play, electrolysis/electrical grounds & dissimilar metal problems.
The bonding wire on my aluminum fuel tank caused pinhole leaks in the center of the bottom section. Bonding connections & aluminum tanks I feel is a NO NO. I can tell you stories of other boats & tank problems because of this.
The flaking paint on my pedestal was due to grounding connections attacking the aluminum (electrolysis) eventually separating the powdercoating. In addition, Dissimilar metal problems were stainless steel bolting into threaded aluminum ie: the mast & boom.
Sure, if your pedestal could use a new coat, think twice about re-hooking ground/bonding connections. On my fuel tank, my ground wire is a quick clip-on that is only connected when refueling for static buildup (mine is diesel, gas is alittle different).
My pedestal compass light was grounded to the aluminum casting. I re-ran the ground (negative) so nothing electrical touches this.
As for the dissimilar metal problems with S.S. verses aluminum, Stu Jackson likes Lanacote. I've used this, Never Seize & others over the years. I just don't want to lose the cut threads in the aluminum. You know, if removing a bolt and a fine powder comes out, that's your aluminum threads turning to dust.
I know I will hear from some detractors on this but, I know what I 've learned in twenty-five years reading all I could find on bonding, lightning protective cones, electrolysis & galvanic problems, I believe the jury is still out. If wanting some particulars in case, let me know in your posts & I will relate what I have found thus far.
