How do I get these off ?
 

I have no idea what these would be called however they have both started to turn silver.

Id like to know how to remove those carefully so I can paint them up satin black.

They are screwed in place.

You need to pull out the rubber weather strip to access the screws

oh so this is in one large section, I thought It was just triangular shape that could be removed, that's not so good.

well I just went out and looked again, seems it is in one piece and where I also have wind deflectors the whole lot would need removed.

So I will mask up the back of the car and paint this small section satin black in the summer., Unless I can have someone make up a decal for it.

Just take all the time you need to prep mate as that's the key to a good job

Decal would not be effective and look good/tidy as a MATT spray finish imo

Yes you are probably right, I will set about it when I do the wiper arms :)
