Here's what I'm talking about.
In this demo the guy sanded with 1,200K, then used a heavy cutting compound, and then polished.
Here, this guy used 1500, compounded, and then polished. Although, I don't care for how his finish came out. The gloss I have now is shinier, and flatter.
And last, but not least, here they used 1K grit and then just used a cutting compound with a wool and then foam bonnet. Seems like they should've went further and used polish...
