Five. Stars just for the polish, the white dressing, trash the spray on yellow quick detailer, quick wax whatever they wanna call it trash. 
This kit kicks butt! I could say all kinds of things but the picture will explain it better!
Don't know what I am doing wrong but I can't get the safety flanges to tighten. I've followed the instructions that come with product and watched a couple YouTube videos and still can't get them tight.
What else could be going wrong?
Hi Mark,
Wanted to go over the basics with you in case there was any confusion. There's two logos on the flanges, one on each side of the safety flange. The unthreaded flange side should go on the angle grinder face, with the logo facing towards the grinder. Then the airway buffing wheel, and finally the threaded half should go last on the grinder's shaft with the logo facing outwards. The last half of the safety flange is threaded, so it should tighten as you continue to thread onto the the angle grinder shaft.

I received the black bar for stainless steel, I was amazed how quickly it brought raw stainless to a shine. I would buy this product again
I'm not professional, but I've done enough polishing with zephyr products to go through 4 or 5 bars of the brown rogue. I've done a few sets a rims and a couple pontoons. The wheels have turned about immaculate and I'm very satisfied but I've struggled with the potoons. I seem to get an uneven product(the finish has horizontal white lines, as well and different things of white where there's slight overlap of sections I work). Everything comes out shiny with enough time but it doesn't seem to matter how slow and systematic I work the pontoons, they have lines no matter what.
Hi Zachary,
Wanted to let you know that when polishing flatwork you have a little less margin for error. Common issues that can happen are more typically on the coloring stage, and we recommend slowing down the RPM on the angle grinder between 1600-2400 RPM or so to see if the lines improve or worsen to your current process. If you have a fixed-speed angle grinder, you can try feathering the trigger, but may be better served with an adjustable speed grinder. The two things to vary would typically be the pressure applied as well as the RPM.
Lastly, you may find yourself needing to rake out the buffing wheel you're using more often on the coloring stage.
First project
Work great. Faster than the older style buffs.
