How would I go about painting my sabers without the paint weathering away?

[Rogue Jedi]

One of the biggest challenges I faced was lining the sabers up, after the handled were fully seated/screwed down.  I ended up using both prophecy end caps, butting the sabers together, and marking the endcaps.  I then took the marked endcaps to a machine shop, who wielded the aluminum caps together, make one connector.  I took some thick gauge (rugged) PVC pipe, and measured the gap between the 2 sabers, and cut the PVC pipe to fill the gap.  Sanded the PVC pipe.  Sprayed with primer which would adhere to PVC, then applied a color I liked.

My original method was to take the original Ultrasabers Prophecy connector and add 4 #17 O-rings (package of 8 is $3 at LOWES/Home Depot).  The O-rings provided enough space/cushion that I could get the orientation of the sabers as pictured above.  The sabers were snug, but duel worthy.





Here is the "cheap" O-ring coupler installed:

If you are speaking of any possible options then powder coating is a good one, as is an epoxy, but to keep the metal texture I would anodize the pieces



(I saw the thread was older so I am speaking to others who are interested)

Your polished efforts look great by the way!

Thank you.

The photos do not accurately capture the polished metal, not sure why. 
The finish for the single saber is more polished than the double-bladed saber (staff).

Anyway, thank you for your positive remarks.
