Hey there Danagrams!
Perhaps a better question would be:
How can I restore the appearance of scratched brifters?
Answer: You can paint them with rustoleum brush paint, model airplane paint, or fingernail polish. If your brifters are gouged or deeply scratched, then you should fill the gouge with either epoxy filler or some type of permanent glue. Lightly sand it down with fine sand paper the next day. Then just paint it! Wait another day, before riding the bike...
