Refreshing Coolant Overflow Bottle

[jharmon]

Greetings,

I have a 78 Z and am refreshing the engine compartment. My overflow bottle has tarnished with age and I was wondering what others have done to clean it and brighten the plastic. Apparently, there are no NOS replacements available and I want to keep the bay as stock as possible, so don't want to replace with a generic version.

Any suggestions?

Thank you in advance.

Well, I felt my vacuum reservoir was rather ugly. It has the same milky, translucent appearance. I painted it black, and it looks 1000% better, but just not stock.

You might try soda blasting it. I glass bead blasted my nylon cooling fan blades with some success. However, I did learn to use fresh and very clean media, otherwise dirt will be driven into the plastic.
