Hi. This is my first post.
Thanks for the opportunity.
I have taken the time to read all of the posts on this thread.
Of course System One is intended for use on cars, but I have used it very successfully for a different purpose - to polish our high-gloss black grand piano. I reported this to Tom and he acknowledged my message to him. I thought I'd also pass it on to this forum.
I am an amateur piano technician and I have been bothered by the haze of scratches on our piano's 45-year-old polyester finish ever since we bought it about 6 years ago.
Luckily, the polyester is applied very very thick compared to that on an vehicle, so even pretty deep scratches can be removed with initial sanding and then final polish using System One.
I started with a spot on the piano's music stand that is relatively hard to see if one is not looking for it, then moved on to the rest of the stand, then to the surfaces of the key cover, then, finally, to the top of the large lid that is most exposed to view.
To be brief, everything that I polished looks like what you would see if you went into your local piano dealer at looked at the beautiful, high-gloss finishes on their grand pianos - black mirrors.
So, if the frustrated owner of a piano comes to any of you detailers or painters and asks if you can remove scratches or "haze" from a high-gloss polyester-finished grand piano, say "yes", grab your Syestem One kit and go for it! (However, if I were you, I would start as I did - on a place that is less visible in order to get the feel for what it takes to polish that material.)
I'm sure the market for polishing pianos and other furniture that have high-gloss polyester finishes is much smaller than that for vehicles, but owners of those things will be very happy that there is a place nearby that can remove those imperfections.
Thanks again for the opportunity.
