Question for the Paint Pros

[PbFut]

Have any of you used this product without the clear coat. (Pictured below)
I used the color coat on my glove box door without the clear as it matched interior so well. I did not want an over glossed finish.
I went to the paint store today and the counterman said it was a mistake not to clear coat as the color coat will not hold up over time and will crack and flake.
Is that the case, and if so, will the satin be the correct shine so as not to be too glossy and match the very good condition original interior paint on the dash.
I want to color paint the AC vent mount and Steering Column as well since the glove box turned out so well.
