Fixing botched paint job?

I painted my duster with summit single stage performance yellow paint and have many areas of thin paint and lots of orange peel. I am NOT a painter lol. I was wondering if I can spot repair the paint, sand it smooth, and clear coat it? Basically treating the yellow like a base coat that I can get perfect and flat, and if I get orange peel or defects in the clear, I know I will have enough build up to fix it.
