What do you guys think about Sonus? I have used 303 protectant in the past but according to the gide at Autopia, 303 and similar products are just putting layer after layer of protectant but dont actually clean.

 

which sonus product?

 

The interior version for dashboards and plastic, supposed to not be shiny

 

I haven't tried the Sonus interior stuff - but I use the Porter Cable and Sonus SFX-1, followed by SFX-2, follower by SFX-3 polish to buff out scratches. Stuff works better than anything else i've tried (Scratch-X, OneShot, McGuires Swirl Remover 2.0, etc).

I also use their car shampoo to wash the car too and it's extremely well lubricated and washes off completely.

Good products.
