Serving SS Splices

[benjiwoodboat]

I've just spliced up my new rig in 1x19 316, and want to serve the splices. But I dont want to promote corrosion. What's the best solution?

Also, only after I spliced them all up, did I find out that one should serve the wire in the thimble. I didnt do this. The wires do flatten out a bit and get loose on the hard turn of the thimble, but I thought, once in place on the boat, the load on the wires would reduce that. How much of a boo-boo did I make if any, by not serving the wire in the thimble?

Thanks,
Ben
