Engine Casing (chipping) Paint

Hello folks !

Quick question:

My beloved 1015 Bonneville is stored outside.
I try my best to prevent rust and all (and honestly I'm not doing a bad job) but one thing I can't seem to be able to control, is engine casing & fins paint chipping. Which only hurts my eyes, but still... annoying.

Someone advised me to get rid of paint chips with a wire brush, and to respray with high temp. black paint.
what do you think ? I'll just like to keep the engine visually clean.

Cheers.

 

Thank you very much for the reply, it's appreciated.
