[Boatanchors] Another (OT) question about the AR-10 Ringo antenna

Sorry about these OT questions, but there are a lot of knowledgeable
people here.
The AR-10 Ringo and coax arrived today and I assembled the bottom
section per the instructions. No problem, it went together well.
Since it's aluminum I DID use some Ox-Gard grease between the mating
surfaces of the ring etc.
The questions:
1. Would it be advisable to either brush on some "liquid tape" or spray
some on the joints (I have both) bolts/nuts etc, or is that likely to
cause more problems than it fixes in the long term. I'm not in either a
high humidity or coastal area where salt is a problem.
2. I'm thinking that I may go down and buy some stainless steel self
threading screws and "secure" each telescoping section as I assemble it,
and not rely just on the clamping action of the hose clamps. That is,
all except the top section, I not screw it together 'just in case' I
want to move it to another part of the band some day. Does that sound
like a good idea?
3. At the same time I'll probably use some of that "Ox-Gard grease
where each section telescopes together. It doesn't say to, but when I
put up my Cushcraft 75/40M vertical (AR2?? don't recall the model) many
years ago they provided grease for that one. That antenna is long gone now.
Cushcraft even supplied a nice coax connector 'boot' for the coax
feedline that they say put on your coax. Only problem is. . . I bought
a pre-assembled cable with connectors already on it, and I'm not about
to cut the cable so I can put the boot on. I'll just seal it well with
the Scotch 2228 Moisture sealing tape and Scotch "Super 88" vinyl tape I
bought for my Tram dual band antenna.
*******************************
The coax also arrived today (both antenna and coax were bought from
HRO). I'm impressed with the quality of the "ABR Industries" RG8x coax
(from what I can see). It's supposed to be USA made, UV proof,
contamination proof and OK for direct burial, has both foil & 95% braid
shielding. It's also more flexible than most of the other RG8x cables
that I have around here. Of course it cost somewhat more than I would
have paid for some Chi-Com stuff from Amazon. Now-a-days when I put an
antenna up, I put it up to stay as it's getting too hard for me to
pull-em-down and put-em-up without some help (though I think this Ringo
will be a piece of cake).
