Hi, I own a Black MP5/5spd. and I love it. Personaly there is no such a product in the market that will last up to 5 years unless you keep your car in the garage at all time, cars that are driving every day needs to be polish and wax at least twice a year, before winter and before summer this is the best timesto do it
If you ask me what is some of the best products on the market I will say Klasse all in one and the Klasse selant, and Zymol products.
One thing is good to do befor you detail your MP5 is to clay the car first and then polish and your final step is the wax is you go with Zymol or the Selant if you go with Klasse this works best.

 

Haha, I know, that one was out of the blue.........

Well thanks alfonso in any case
