I have this on both sides of the car ... what to use to remove it?
No idea what it is ... must have drove over something.

what's a good all around tough spot remover / cleaner for these plastic trims?

 

This stuff does what every other product claims to do but is more economical when used correctly and lasts much longer per application. In other words, the best in the business. You can't go wrong.

PS: I just noticed you are a 6th gear denizen of NAM which surprises me that you aren't familiar with Richard 'Octaneguy' and his detailing goodies.

 

^^^ + 1 Pre Wow & Black Wow

 

Thanks gentlemen ... i always was under the impression that Black Wow is just a product that restores "black" plastic ... I guess Pre Wow is a strong cleaner?

And yeah ... 6th gear ... on my second MINI since 2003.
I live in NYC and drive the car daily in the hellish conditions it provides.
Detailing ... MAYBE once a year.

 

I'm guessing your black 360 has never really been treated or maybe just once or twice (oh dear ) so the Pre Wow then Black Wow would be called for. Just give the li'l guy a bath with any good car suds then go to work on that black stuff. You'll be glad you did...and may even be inspired to detail, say, twice a year or more from now on ?

 

How many uses does one usually get out of the 2oz black Wow and 4oz Pre Wow?

 

I've done mine 3x since I got it. 2x back to back days because it soaked in a bit. The 3x a week later and it's been perfect for about 6 weeks give or take a bit.
I just finished washing it and the water still beads and wipes off great.
I got the 4oz bottle and have used less than 1/4 of it. Great stuff!

 

Watch the video Richard has on youtube. You'll see how little he uses. The bottle will last a heck of a long time if used as directed.
