yea 1 of em is down to metal, others just removed paint 
if it's down to bare metal i don't quite know how you're expecting to remove it by polishing?

you'll need to sort that as it could become a problem... as i see it you have three choices
1 paintstick - use a cocktail stick or something finer... do not use the brush supplied as they are way too thick
2 rattle can spraying yourself... you can get the paint mixed by quoting your paintcode to your local friendly dealer or I think someone said halfrauds mixes it up too? needs time and patience, and then some more time and a lot more patience, it's all in the preparation, there is a sticky on it somewhere around here.
3 find a decent paintshop and see what they'll do it for... might be that for a bit of beer money they will sort you out... make sure you go to one that is recommended though
paint is always a tricky one and as far as I see it you'll get increasing results the further up this little scale you go. personally I would go for option 3, but that is just me because I have OCD and know a good paint shop so i know it will be done right first time!

and I know I would make a hash of the paintwork... but plenty of people have a crack themselves.
