polishing question

Ive managed to polish pretty well except areas where my finger is too fat to contact....eg, curves...so whats the best way to get these areas polished up aswell?

also, during polish, it is very easy to take paint off edges and raised areas...what will be the best way to touch up these again with out screwing up the polished paint job...its just the edges that realli bothers me because its just a different colur...for black edges i can use a black marker but now im building a red one and its harder to find a red marker that matches my body colour.....

thnx guys

1- cotton fiock (Q-Tip?)
1a- if you have a son I'm sure his fingers would be thiny and small enough :D LOL (he would also be happy to dirty up your lovely build!!)

2- you'll learn with experience how avoid to strip edges, meanwhile you'll mask with thin strip of masking tape

3- you'll easily (and convincing) touch up with a good airbrush and low pressure, doing several thin passes (if I remember right somenone - may be Mark?) made a good tutorioal over the summer)
