I've got a few scratches on my bike. I have lots of nicks from gravel on the tubes that connect to the bottom bracket, chipped paint on the front forks and a huge gash along the top tube. The scratches that have gone down to the metal have rusted over.
I plan to get some touch up paint to go over them (or at least go to my local hardware and car stores and ask if they can match the colour), but I have a few questions.
1). Do I need to get rid of the rust before I coat it in touch up paint? I don't want to sand it since it could damage the paint around it.
2). Do I have to lacquer over it? Some touch up paint doesn't seem to require lacquer, but should I lacquer over it anyway?
3). How do I deal with scratches to the lacquer, but not the paint?
