Hi all

We got front gates made about 3 years ago and the finished gates powder
coated in black. The finish was fairly matt rather than high gloss, and
they have been fine up until now. When the brighter evenings came along,
I
began to notice they looked very dull and almost grey.

So tonight I went out, armed with a bucket with Flash in it and a sponge
pot
scourer thing. I gave them a good wash but as they dried I realised that
it
has made very little difference, apart from removing a bit of grey-green
dust from around the bottom.

They almost look like an old car that needs T-Cut. Is this the case, and
if
so, would T-Cut for black cars be off any use?


Might be worth trying some of that Back To Black stuff used for car bumpers

I was going to suggest that, but it doesn't last very long. It's mostly
silicone oil which is good for a quick tarting up but would weather off
quickly.

You'd have no chance of painting on top of it either, if you later
wanted to try paint.
