Hi Pete and all, From earlier posts on this subject I would still suggest
that anyone desiring UV protection contact their nearest marine supplier.
The marine environment is probably the worst case for UV damage so
consequently these manufacturers and distributors usually have the best and
latest products including UV protected canvas, carpet and other products
needing protection. Point being they are really tuned in to the problem of
UV on many items.
Marine surface coatings cover a wide range of applications so I have no
doubt that you would find something to meet your needs, and it probably will
actually be somewhat effective for UV protection..I suspect most "UV"
protectant additives (or claims of such) are not much more than rubbing it
with coppertone #12 :). Any fiberglass product manufacturer, ham antenna or
other can dump a bottle of coppertone into the mix and claim UV protection.
Time will tell on that.
Try West Marine, Boat US, Boaters World..I have always found that these
operations have a good selection to meet most needs, and they will talk to
you over the phone if you have questions...what a deal! 73, Tommy WD4K

Is there a kit to remove the sag of the elements on the pro 67-c? If
not, how do you who own the antenna remove the sag?
Thanks

Con: I suspect that others would also be interested in what UV
protective paint/ epoxy to use and where to buy it. However, I have not
received any comment on the question.
How about it, anyone have any ideas/ suggestions?

From my experience managing a painting project at the plant, the
outdoor chemical pipelines were coated with an epoxy but since that's
not UV resistant, the contractor top coated with polyurethane which
is/had a UV additive. Contact your industrial paint supplier and
inquire. Phil KB9CRY

This may be relevant -- Wal-Mart and K-Mart sell a Krylon product called
Fusion that is touted as adhering to ANYTHING -- including glass, PVC,
etc. Other makers are also selling plastic-adherent paints now, so this
may be an option, though I'd be a little skeptical about the chemical
compatibility with whatever coating the SteppIR elements already have on
them.
In my case, I just want to protect some cheap Rubbermaid Rough Totes that
contain my shunt feed and antenna switching boxes, and I think one of these
spray products will do fine for that. As I understand it, the important
thing is simply to hold some opaque pigment between the plastic and the UV.

And also make sure it's electrically transparent/non-conductive.

>From my experience (25+ years) owning a now rather old
sailboat I can attest to the fact that epoxy based products
are NOT UV resistant. Polyurethanes are the way to go.
Epoxies breakdown quickly (approx. one year here in the
Pacific Northwest USA - a very forgiving UV environment).
Further, when we use epoxy based products for boat repair
virtually every manufacturer suggests/recommends over
coating the epoxy coating/gluing materials with something
other than epoxy based paints - polyurethanes being on the
top of the list.
One note of caution... There are some paint products out
there that advertise themselves as 'single part
polyurethanes' but if you look at the ingredients label you
will find that they are composed of 'alkalyd resins" (i.e.,
think good house paint). Despite the labeling they are not
true polyurethanes and will not hold up as well. They may be
perfectly adequate for your use but they are NOT true
polyurethanes but rather an advertising gimmick taking
advantage of a rather wimpy "truth in labeling' law.
As Steve, K7LXC mentions in another post - "RF transparency"
is another issue. I can only address the 'paint life" issue.
Real polyurethanes (typically 2 part) are toxic, and
(depending on formulation) can be difficult to apply some
mandating spray application although others are specifically
formulated for brush application. Most all polyurethanes are
TOXIC and deserve considerable care in application. Spray
being by far the worst case scenario. To paraphrase what
Steve has said numerous times ".. Follow the d!#*
directions..." the really good stuff can be dangerous if you
don't pay attention.. The typical 'nuisance' dust mask is
NOT appropriate if you intend to spray these materials.
Follow the manufactures directions. The brush-able materials
have a very good life span but by virtue of formulation and
the absence of the mist associated with spraying are far
less hazardous to your health. Read and follow ALL
directions on these products.
Also note that some products will suggest/recommend an epoxy
undercoat and a poly overcoat. This is to ensure good
adhesion to the underlying fiberglass (typically
polyurethane based resin coating). The entire "fiberglass"
materials field is filled with complications at the chemical
level. Following the instructions is once again key.
As other have asked in this thread "...What does the
manufacturer (Steppir) recommend?" That's really the main
question of the day.
