I would like to replace it, so as to avoid continual repainting, but how
can I tell if a replacement dish won’t go rusty? Are Sky dishes made of
aluminium? Is there a recommended manufacturer or source?
Grateful for any advice.
These are horrible, cheap, rust-prone things that cost Sky only about
£3 and are designed so that you have to keep replacing them at the
cost of a call-out. Here, where we have wind-blown salt spray off the
sea they last for an average of 2.7 years. So I invested in a
galvanised dish guaranteed for 10 years, about £150 installed by a
private contractor. Well worth it.
When you say the dish is rusty, I assume you mean the metal support and
the arm holding the lnb. I think most of the dishes around here seem to be
made of some sort of plastic.

Does the dish still work OK - i.e. are you still able to receive a
good signal at your STB?
If so, treat it as you would your garage door - paint it - far cheaper
than replacing it :-)

Yes, there's no reason why you shouldn't get the rust off (you can buy
that chemical stuff from motoring shops) then paint it. If you replace
it you could paint the new one.

The eBay seller described it as a Sky dish, but as there was no
branding whatsoever on the packaging I was wondering if it was just a
cheapo tin copy. Perhaps the official dishes simply have more paint on
them. Anyway, I’ll try a clean-up and coat of paint, and see how that goes.
Thanks again.
Then apply wax?

Or maybe aerosol smooth dark grey Hammerite?
I thought of Hammerite, but doesn't this contain metal, and so likely to
interfere with reception?

I have used ordinary aerosol spray paint without any apparent adverse
effects (and that's why I included the question mark) however to be absolute
be honest, I would be surprised if it did.
Buy another new one, but after you install it paint it with a thin coat of
WaxOyl. It will last for years and years.
I bought a dish off Ebay about 5 years ago for about �12 including the LNB.
When it arrived it was a Raven dish and has been excellent for my parent's
"freeSky" and looks as good as new despite 5 years in the Welsh rural
climate!
My own dish here was on the house when we moved in some six years ago and
although unbranded and a dull matt grey colour, it shows no sign of rust. I
wonder if you've just got a rogue dish with an insufficient paint covering?
New dishes are pretty cheap, and I'd be tempted to replace it rather than
messing about rubbing down and painting it.

I'd doubt if it would matter, the disk itself is a reflector. As long as
you are not painting the LNB.

Would they have been able to charge extra for replacing the dish and
thereby making some extra money?

But he just said that it *WAS NOT* a genuine Sky dish!!!!!! Just one off
eBay which was far more prone to rust than the Sky ones.
A galvanised (hot dip, not electroplated) dish will last the longest,
preferably painted aswell.
As for protection or repainting, you could use galvanising paint such as
Zinga (96% zinc), but this will form a new dish (as it is conductive)
and unless you spray it, it may affect the S/N from the dish due to the
irregularities of brushing. However rust doesn't seem to affect it much
so maybe it doesn't matter. Zinga, or Galvanised surfaces can be top
coated after using an etch primer.
If you really want to do the job properly you have to strip all the
paint and rust off, and re-coat with at least zinc electroplate, primer
and a good top coat. However the rust may have caused pitting and that
again may cause problems with S/N.
Internal rustproofing material like waxol may not stand up to UV,
regular rain washing and may also collect dirt.
Frankly there are no easy answers and hopefully you can see that
re-coating a dish takes many stages and alot of hard work, if a new dish
cost £60 I would go for that. You are not going to do much good with a
brush and a pot of paint alone.

Most certainly� But as other dishes in his area which HAD been installed by
Sky were *NOT* rusting it was a fair guess that it was a cheap copy!
Certainly more probable than immediately slagging off the quality of all Sky
dishes!
I assumed at the time that they bill Sky for all "necessary" work done and
that this little "extra" would have been added on. I paid nothing more than
the standard install fee.
Triax make a range of fibreglass dishes which are not that cheap but
they will stand almost any weather conditions.
Hammerite is highly reccomended.
Last time I looked, Morrisons had small tins easily enough to coat a dish in
metallic silver.
I've still got a working 20 year old original Astra 19.2 dish on my house
picking up the German and European channels with a receiver that has been on
for 11 years!

As it is presumably a fixed dish, you really should fit a monoblock
so that you can get the stations from Hotbird 13 East as well.
