I put on a second coat today and you could see a difference.....my black plastic interior has never had any type of treatment....it’s a 2011.... it did a little to the plastic ...maybe I didn’t use enough....but I was more oncerned with getting the outside done...the inside needs a sweeper and a good cleaning.. I used it on the tires too.....it doesn’t shine like other products.. but then again I didn’t soak them....didn’t want to waste it.
My thinking is as long as the paint beads the water making it run off that’s less dirt sticking to the paint...so acid rain should run off too.
I washed it with plain water first...
Didn’t need to dry it...the breeze dried it. Because of the first coat..the water dripped off.
