The SteppIR poles are coated, and there is no recommendation for
additional painting, but some folks do that.
I was a bit concerned about the UV longevity of the heat shrink that
goes over the tapered sections joints and placed a layer of 3M silicone
self fusing tape over them on my 4L. That is in great shape after 8
years, as is the FG coating.
The trombone elements IMO are effectively linear loading when the tape
extends back towards the EHU on the 30 & 40m capable antennas. From
experience with my newer DB36 on 30 & 40, it is sensitive to nearby
loading effects, so there might be some retuning needed from a paint job.

I am wondering if antenna manufactures such as SteppIR recommend coating
their products before installation? Do they use fiberglass with UV
inhibitors?

Thanks for all of the respones. I'll be using some marine paint on the
antenna. Although here in Illinois I may be able to find automotive
paint easier than marine paint.
Thanks and 73's
