Good, expensive, and How!

I often have to renovate Kunsstoffoberflächen of all kinds.
This begins with the six cell phones family, incl. 3, which are used by the children and stop with scratched DVDs and Kunsstoffoberflächen all kinds.

Rule no. 1:
If you want to remove deep scratches, then you used to and different polishes the series, with different efficiencies, lubrication and working pressure.
Displex is not suitable for the main operation but for the past.

Rule no. 2:
A polish is only as good as the one who uses them. You need patience, patience and again patience, moreover, a lot of tact, especially in the final phase.
Circular movements and feel of the material are required. The efficiency can be acoustically assess if you put your ear up close.

Rule no. 3:
The polish is not enough. For effective work you need clean microfiber cloths (optical quality), very soft toilet paper, a little washing up liquid (or Palmolive etc) and of course clean, best warm water.

And so it is done, in order:

1) Used 800 he sandpaper, wet, hot water and 40% Palmolive / Spüli / Pril, with very little pressure.
Thus the rudest scratches are removed, but of course countless microscopic added.
The sandpaper should only be used to eg wet Messser or other metallic objects 2-3 minutes to refine the grain size and to alleviate the grinding action.
This provides a grain size that corresponds to about 1600 to 3200 and is suitable as a glass polish.
In this operation, the sandpaper must often be rinsed under running water and the screen to be cleaned with a soft sponge or wet toilet paper regularly gently.
With this operation, approximately 80% of the material removal is done.

2) A1 Nano Scratch Polish by Dr Wack, lubrication with Nanotec A1 Speed ​​Wax Plus 3, medium to strong pressure
Thus most fine scratches are removed, there are still countless microscopic scratches.
As carriers are soft lint-free textile support, best suited microfiber cloths.
Takes the polishing operation for a long time, the cloth should be washed or changed in between.
With this operation, about 10-15% of the material removal are done.

3) final polishing with Displex, first without the addition, after one minute with small addition of water with 30-40% Palmolive / Spüli / Pril, medium pressure, last light pressure.
As support: Microfiber cloth for optics, moistened.
Thus the microscopic scratches polishing operations 1 and 2 are removed.
The material removal is very low and should not exceed 10-15% of the total polishing operations.

4) wiping with clean optic Mikrofasetuch or quality toilet paper with pure alcohol from the pharmacy, very little pressure.

Miracles do not exist: If you want to remove deep scratches, it takes patience, patience and again patience.
At worst, it takes up to 4 hours and sensitive fingers, just in the final stages.
If we make it right, but we obtain a surface that is at least as good as a new one.

Is Kunsstoff little zerkratz, one catches of course only with operation 2 or 3 on, depending on the.

Under these conditions Displex is an excellent product with high efficiency, but only for the last step.
In my opinion, it is overly expensive, but good and effective and I know nothing better.

If someone complains that he does not get scratch off, then it is certainly not at this polish.

Who wants to renovate a really ruined display, can also be used for the preparation either Autosol Stainless Steel Polish or RX-polishing of Volker Schmidt GmbH (lubrication with cooking oil, cleaning with washing up liquid / Palmolive etc).
But be careful: This stuff is not suitable tremendously effective and for beginners!
