Have been a dedicated Zaino user for close to 2 years now; initially on dark blue Grand CHerokee. Now have a "steel gray" metallic Saab 9-5 that looked great with Zaino, but not real "deep". The Blackfire topper REALLY brought out the depth and metallic flakes in the paint. Great reflective shine with more color. Very pleased ! And as an added bonus, I was collecting MAJOR dust with Zaino alone; this prob has now been minimized. Thanks to those of you who initially tried this combo; great results :bounce
