Default Preferred Spreader End Corrosion Prevention?

I have a Spencer 44 with aluminum spars. Apparently I was a little overzealous in my last application of rigging tape on the spreader ends for temporary chafe protection. Water seems to have accumulated inside the tape and when I removed it to sew on some boots there was quite a bit of the white aluminum corrosion products in the groove on the spreader end. Obviously I didn't have enough stuff between the stainless wire and the aluminum spreader end to prevent the galvanic interaction and there was also no place for the water to drain out. My spreader ends are all aluminum and just have one groove for the wire and two small holes inboard for the stainless seizing wire to run through.

My question is: what is the preferred method for insulating the wire from aluminum spreader ends?

I was going to slather on anhydrous lanolin but should I use something like teflon tape to parcel over that? I don't really like the idea of getting too much squishy material in between the wire and spreader end that will compress and loosen later.
