The product discription states that you get showroom results in minutes, and this it does.
I deliberatly left the plastics and vinyl untreated for a few weeks. Continued to wash the car as normal and after about 5 washes, the trim was ready for the 1st application of Blackmax.
Using a microfibre towel for the application, I put a small amount on and applied firstly to the side door trims.
After doing so, I was well impressed with the results, showroom black !
With other products, you apply, and after a few minutes they seem to fade a bit and require a bit of a buff. No need to do this with Blackmax. If you do have a bit of overlap or get it on the paintwork, it wipes of easily.
The product repells water for a couple of weeks, no sign of any runs.
I would definatly recommend this product to anyone as part of their car care regime.
10 out of 10.
Going to order a 16oz bottle myself and am really looking foward to having perfect trims every time I tend to the car.
