Is it OK or recommended to use spray/shine stuff on the dash? I personally don't like the look of the glossy dash, but I've always been told it protects the dash from the sun and my car is a non-garaged car. I read in the manual not to use a "glaze" - would these products be considered a glaze since they are so greasy? I purchased a Meguier New Tech type - but it was extremely thick/greasy so haven't used it. Should I just stick with a dry wipe to clean the dust? Any recommendations? Thanks.
