Vang Tang Replacment

[Acadian]

When replacing a Laser vang tang does the Tef-Gel, anti corrosion paste, need to go between the whole tang and the lower mast section or only at the Rivets?

After replacing the tang with just Tef-Gel on the rivets and in the holes I cleaned the old tang. I noticed the old tang had some mystery stuff on the back and I'm not sure if it was old anti-corrosion paste or just salt and other gunk that had deposited . I'll do it over if needed.

Gel goes anywhere stainless touches the aluminium. I've just scrapped 6 Pico booms and two top mast sections because of electrolytic corrosion £1200 down the drain..........

I just re-riveted my gooseneck to the boom. SS gooseneck and SA rivets. I used that "goop" on all the rivets and between the gooseneck and mast section

Thanks. I'm going to do it over with Tef-Gel between the tang and mast too. At the least the gel will keep some salt and sediment from getting in there.
