Oh yeah. More than enough especially for those light surface scratches. I recall one day I dropped a lid and chipped it. That porcelain layer was a good half mil thick. That is WAY more than enough to do some pretty heavy polishing
Sounds good enough to me to try it should the need arise. I got a hold of a used S&W model 629 some years ago that was all scratched up. I used a product called Flitz and my Dremel with little polishing pads to not only get all the scratches out, but to polish it to where it looked like it was chrome plated. I couldn't believe how nice that gun looked when it was done.
Oh Flitz is great stuff. Many years ago I restored a 1967 Moto Guzzi V7 that the previous owner had seriously trashed (even having set it on fire). Much of the polished aluminum had been rendered horrible. (wheels, valve covers, the polished gas tank sides along with some other parts). I spent weeks polishing those parts back to their glory by hand. My fingers still hurt close to 50 years later
I used Simichrome I did not own any powered tools to do it with back then
