CB antenna mount grounding question

I’m far from electrical savvy. I’m going to have a Rugged Ridge CB antenna mount at the spare tire carrier.
Do I need to strip the powder coat out of the antenna stud mount hole?
Do I also need to strip the powder coat out of the bolt mounting holes/entire reverse side of the mount/face of tire carrier?
What about rust? We rust quickly in MN

Cb must have good ground so yes must be bare metal for all ground connections and I also ran ground wire to my terraflex hinge for better ground as well

Don't strip the powder coating out from inside the hole, but you do need to strip a ring of powder coating away from around the hole underneath the mounting bracket. That allows the top of the bottom half of the antenna mount, labeled SO-239 Coax Connector below, to have an electrical connection to the mounting bracket above it.

Make sure the spare tire carrier is well grounded to the tub by insuring several of its mounting bolts are contacting bare metal on both the carrier and where it's bolted to the Jeep.

And ESPECIALLY make sure that you assemble and install the antenna mount exactly as shown here. Take care the nylon Insulated Shoulder Washer, shown below, is present and located as shown. If it's not the antenna won't work.

I'm in the salt belt. We have salt slop on the roads for at least 3 months of the year.

I have a Teraflex antenna mount bracket. The design is very similar to the Rugged Ridge. I stripped a little bit of powder coat from the top and bottom of the mounting bracket then mounted the hardware.

I removed just enough powdercoat so that the hardware would cover the bare area completely and no unprotected metal would be exposed. It's been there for two years now and there have been no problems with rust.
