This stuff is amazing. Definitly keeps car cleaner for longer, still gets dirty but not as much as prior to opticoating. I highly recommend Alpha Auto spa/Brian Cheng to opti-coat your car.. he did the interior as well and vaccums and cleans your entire car pretty much at a very reasonable $$. I think hes spent over 15 hours on my car as you can see how dirty and muddy it was when I delivered it to him... pm me for his contact info. Thanks again Brian!
