Single stage paint question
Not a tech/performance question but I'm hoping someone on the forum has some experience with singlle stage paint.
I painted my C3 with the help of a good freind who was a paint and body guy his whole life. Unfortunately he has since passed so I'm not sure what I'm doing wrong here. I have a small area on the car that needed a touch up. I preped the area and mixed the same paint that was used on the car with the hardener and reducer you see on the attached pics using an airbrush. the coverage looks great after spraying. After letting it dry for a couple of days I tried cutting and buffing to even everthing out but I get a very faint dark shadow that developes on the newly painted area. If I try to clean the area with laquor thinner after it's dry I see the newly painted area interacts with the thinner. No issues or reactions with the original paint . I know very little about this but I'm assuming that I'm not adding enough of one thing to too much of another.
Any suggestions?
Thanks

If you zoom in you can see a very light but noticeable darker shadow. It gets worse with buffing.
Hardener I used
Reducer I used
Same paint brand and color used to paint entire car
helpful to have 2 guns spray the area then 'melt' the edge to melt into existing paint..then buff..

i bet the paint you used had a cheat sheet..
I’ve never had good luck with touching up single stage and metallics.
