I followed manufactures 8:1:1 ratio (thinner and hardner).
I'm confused.
You said you used ALK-200, but the data sheet says 15:1 paint to hardner and up to 10% xylene. If you used 1 part hardner (ALK-201) to 8 parts paint, that sounds like too much hardner, and that would be 12.5% thinner.
So wheels are free of chips and stay like new with automotive paint?
One caution about powder coating. If it does get chipped, rust will tend to grow under the coating and it will start to flake off in big chunks. I've seen that on items that came to me with powder coating. I had my wheels powder coated, but may wind up redoing them if they get too bad.
Regular paint can be repaired more easily.
