Good afternoon,
I have a hammock with metal poles. Sometimes the weed-eater gets a
little too close to the poles and will chip the paint and along with
the morning dew and rain, the poles have paint coming off and rust is
forming.

After getting the old paint off, sanding and painting the poles is
there a type of spray that will put a rubber coating on the poles to
protect them from further weed-eating? I know there's a rubber
coating you can dip tools in to form rubber around the handles.
..
I even thought about getting some type of pipe/pole covering that
would prevent the weed-eater at chipping away at the poles.
Is there any type of covering? Anything along the lines of pvc pipe
that I could use to fit over the poles?

I would prefer not to put weed killer around the hammock. Besides,
with the poles being on the ground rust would eventually form again.

Thanks in advance
Elliot
