The winter setup (641M) I recently bought has some rash so I figured it was a good time to change em to black. Would look much better on my HS M2C. Went the DIY route and got some DipYourCar's Hyperdip in shadow black. 4 cans of dip and 1 of cleaner ran me about $60.
The product I must say is much much better than traditional dip. Significantly smoother spray (goes on like spraypaint), satin finish and feels much less rubbery/grippy. It is very thin so it can drip if you spray it on heavy. I had to be very careful and still got 2 drips in total. They're barely noticeable since they were probably on the 4th-5th coat. Did about 11 coats in total so it should hold up great.
Overall very happy with the results.
1st light coat (50%)
2nd light coat (50%)
3rd normal coat
Lost count of coats, used 1 can per wheel was probably about 10-12 all in all.
Finished product
Will probably put them on the car sometime next week, excited to see how it looks
