Anyone else ever get mad at Zaino?

I use Zaino exclusively, and love the results.

I have not used the Z-PC product. Don't know about how it works on swirls.

I have never had any problems using Z2 or Z5. Always easy to remove. Did you use too much?

If Z6 leaves a haze, wipe the panel with a damp rag, or mist with distilled water, and re-wipe/re-buff. This will remove the haze. A haze indicates that you are using too much product.

You should call or e-mail Sal Zaino in the morning. He is very responsive and stands behind his products.
