What sort of dish was yours, mine has a flat black finish to it, don't think it will polish up, didn't know the surface of the dish was that important as long as it was smooth and not dented in any way.
Hi jon641 - My dish is just a large dish nothing special (no dints) & the polyglaze restored the surface back to the way it was when I bought it in Katherine NT 4 years ago.
If it didn't make any difference I would not have posted the hint.
The technical term for that is the Placebo effect.
The dish works by a metallic (or metallic compound) layer reflecting electromagnetic waves and focusing them onto the LNB. As long as the dish isn't dented or damaged it will work no matter what the surface looks like. But it's nice to bring things up to good looking condition anyway.
Cheers

I thought the dish had to be matt in finish. I can remember reading that you can paint a dish any colour you like as long as you don't use gloss paint.
The only effect gloss paint "might" have is to reflect more light/heat onto the LNB. I wouldn't expect it would be that serious a problem though. Even painting with metallic paint seems to have little effect from what I've read. Now if it was within a radome, you wouldn't paint it with metallic paint.
