<DIV>The reason we use the vaseline, is that it remains conductive, so we can
precoat the connectors before assembling and tightening. (Windy Dankoff taught
us that one)
<DIV>I would see the 3M coating as something to spray on after, but I would be
concerned about using it on contact surfaces before.</DIV>
<DIV>I agree, heat can be an issue, so we use a high temp grease for
applications were the temp might get over 100 deg F.</DIV>
<DIV>Maybe a combination might work best: grease on the contact surfaces
before, and 3M spray outside after?</DIV>

<DIV>We use the “inner melt” type of heat shrink and have had few problems
with it compared to the standard heat shrink. As far as Lead plated lugs, I
am not sure I see much advantage to them. Also as far as coatings go, most
Vaseline and other standard grease type are way too temperature sensitive,
and in hot weather they just melt away – and they are also great
dust/bug/dirt gatherers. 3M and others make a spray on coating that hardens
somewhat that we have found to be much better. From the 3M website “<FONT

electrical-grade, fast-drying enamel sealers and insulators in pressurized
cans.

<DIV>Where do you get the lead plated lugs? We used to special order tin
plated lugs from Del City, but they quit carrying them.
<DIV>I found that the grease or vaseline coating was the most important
issue, though. Tin plated lugs would corrode just like the unplated ones,
except they first would lose their plating.</DIV>
<DIV>Lead plated lugs might just be the ticket, except you would still have
to keep the corrosion from creeping up under the heat shrink to the copper
cable.</DIV>
<DIV>I've had cables with corrosion going up the cable strands for over 6"
past the lug. And yes we use heat shrink with the sealing adhesive inside;
the corrosion just travels right under it along the surface of the metal. I
actually found electrical tape seals better, it just doesn't look near as
good, so we still use heat shrink, and coat over the heat shrink with the
vaseline (or grease).</DIV>
