I thought that with all the knowledge on clear coats displayed in recent posts that my question might be best answered here.
I have purchased cheaply a full groupset (DA 7700) for my project bike, but the cranks have a well loved look to them.
I thought that I could polish them, but have realised that there is a clear coat of some sort over the metal. This coating would be sanded off before polishing.
Once polished, I won't have a protective coat. How much of a problem will this be with the alloys used to make cranks? Will I have to re-polish often? Will a standard cleaning product (ie alloy polish, car wheel type?) be ok? Should I get a clear coat put on the newly polished metal (I can get two part polyurethane done easily at my work)?
