I was wondering if your Diamond Clear Metal Aerosol is UV stable? I have an open engine track roadster and would like to use this on the polished “lower temperature” polished engine parts (pulley’s, valve covers, etc.). I’ve used the Extreme Diamond Clear on the heads, intake, etc. and found it to work well in our high UV environment (Colorado at 8000′ altitude). Can I expect the aformentioned product to stand up to the UV and not “yellow”? Thanks in advance.
