single stage vs base coat clear

I was told that if you use single stage that you can spray a clear coat after you spray your last coat of single stage. Not sure because the tech sheet I gave tells me clear coat is not recommended. I'm not even sure if this would be of any benefit unless it adds more durability to the finished product. Any Thoughts?

What product are you working with? I have done many with clear over single stage, you just have to be careful you don't re-float the metallic when laying on the clear.
