Holding up really well. Watch Youtube...plenty of information there. I used 4 cans to about 25% left in each can. I waited 30 min between coats and did very little each coat. I recall about 5 applications done very thin each time. I finished off with a can of metallic sparkle. It appears to be only metallic add-on and no plastidip, so its really easy to apply. I only used about 1/2 a can total...maybe even 1/4 of a can. I did the wheels while on my truck. I only removed the center caps.
Total cost was less than $25 from Amazon and I did it just to test black. I love it.
If you have the means, removing the tires would allow better access to all surfaces. Mine is fine but I can see a few spots where I didn't get in the corners as much.
