This past weekend I tried Nu Finish car polish on my Z and wanted to pass my observations onto anyone who's interested.

When I first applied the polish I used too much...so don't use too much at a time. I found it best to use a little at time on a wet rag and apply in a circular motion. I believe a cloudy day might be better than a direct sunlight day when applying the polish.

Another thing you might want to note is this; If you get the Nu Finish polish on any plastic parts it will stain it. Of course I found this out the hard way thinking I could just wipe it off the plastic with a wet rag...not a chance.....
It stains it white and looks terrible.

So I checked the internet and and followed another persons suggestion of using smooth peanut butter on a damp rag to remove the white polish staining off my plastic parts and it worked awesome!

Not the most exciting post but might be useful to some.

 

When in doubt, read the instructions.

 

This an important point. I just wish the instructions would have provided a warning not to allow any of the polish to touch the plastic parts.
