After using S20 Black on a few occasions, it doesn't seem to be as good as it's hyped up to be. At one point I did think it could be done to my machining skill, then threw that thought out of the window.
My initial experience was on my 11 year old daily driver VW Touran. I put this down to German paint and the car being so old.
Recently tried again on a Vauxhall and Honda (much newer vehicles with less paint defects) and still had to go with three passes.
Not quite a one step polish as it makes itself out to be.
Using forced drive DA, speed 4/5, Green & Orange CG Hex Pads.
Am now wanting to sell/swap this and replace with something.
can you explain "...and still had to go with three passes." please?
When doing the usual 18 to 20 inch square it is usual to continue going up and down then left to right continually until the polish is spent. This might be 2 passes it might be 10.
If the amount of cut is not what you expect or the defect is still present then you would reload the pad and go again or you would get a more aggressive combination and try again.
A one step polish as I understand it is one that has diminishing oxides that as the polish is worked act like a compound at the start and a finishing polish at the end which is even more reason to ensure the polish is fully worked.
An alternative to S20 is Sonax Profiline Perfect Finish. I used this on recommendation from someone on here and was really impressed with the results.
Jon at youtube Forensic Detailing did a comparison between the two and found the Sonax a better product.
Personally I haven't used S20 so can't make the comparison myself but can recommend the Sonax.

I used it earlier in the week, Was more for refinement with the Flex 3401. Pads were Sonus SFX 2 and LC HT polishing pad, the latter pad it really didn't like for some reason and was rather jumpy. How did you find removal, my results where fine but it could be hard to remove, it improved using less product and allowed me to work it longer which sounds a bit of a contradiction. I started off using the same technique as in Jon @ Forensic Detailing's video, plenty on the pad, reasonable size area and a slow arm speed and long work time of around 4 mins but at speed 3. wasn't great to remove was chalky like it had dried out rather than leaving a thin film that easily wiped away
3 passes sounds about right. A one step polish doesn’t refer to the amount of passes needed. It simply means you can use it as a cutting and finishing polish (by using different pads).
It’s quite e a nice product, but a bit of a jack of all trades. If I need a heavy cut I’ll use something else.
Just goes to that detailing has a massive difference of opinions. I have used this on 3 black cars a 2016 Ford Focus, 2016 Ford Fiesta and a 2017 BMW 440. I absolutely love the stuff!
I do use it with the Scholl Purple Spider pad though. I was thinking of trying the Sonax to compare it. I also like the look of the new Angelwax Enigma AIO...
I did wonder if the pads were partly to play. The sonus pad was much nicer to use than the LC one. I should have tried it on the G220 see if it made any difference over the flex, prefer the latter to use though. I bought it as been a big fan of other Scholl products, S17 and S3XXL are a dream to work with.
The Flex 3401 doesn’t work well with microfiber pads. For heavy cutting a wool pad would work better.
