I did not believe it, but it actually works! One only needs to have time, energy and a really good polisher and felt polishing pad. I got hired a Festool. Only I have the disc washed thoroughly. I have not used too much water, the places and polishing felt very slightly misted with water. To polish the work of my windshield took about 2 hours. Here you get arms like Popeye :-) In between, always wash the plate clean and controlled. The result is amazingly good!
