Hi I have a Silver 2015 Zafira Tourer SRi , had it a couple of months and absolutely love it. It has Black alloy wheels but I think I would prefer Silver. Can I just paint them myself or does it need to be done by experts? I have limited DIY knowledge and equipment 

You could try painting them yourself but to get them resprayed properly it would cost quite a bit

either way you would need to remove the tyres to paint them properly

Maybe worth trying to find some silver alloys and maybe swap for the black ones?

Must admit, I prefer silver rather than black wheels. I do have a set of black alloys that will be getting a coat of silver whilst it's nice warm weather.  Black wheels suit dark coloured vehicles better in my opinion.
