Around May, I couldn't see the bike logo at all, so I ordered and used a polish. To be honest, I didn't expect much, but... the difference was noticeable.. Since the original frame was matte, that might have played a role, but even considering that, it seems like this bike has satisfied all the parts I regretted.
I used a product called "Eat Off". It smells like cherry and seems like a good product.
The bike is a Merida Reacto 6000.
