OOPS - frame paint has a problem

[BA.]

I trust you guys with actual painting experience way more than I do the guys at the local shop selling stuff. Experience counts.

I painted my frame with that Nason Chassis Paint I mentioned in my other thread and it/I did pretty good.....EXCEPT.....

I either had crap in the air or overspray got the best of me.
Most of the vertical surfaces are fantastic considering I'm no painter but my Horizontal surfaces...the tops of everything, ...has a slightly rough, texture-y feel. Not orange peel, ...it's worse.

I need to repaint it. I've scuffed / resanded the top surfaces of everything already.
** Can I get away with the 'rolled over tape edge' trick and only repaint the top surfaces or do I need to basically sand the vertical (side) surfaces too and repaint the whole thing?

It's no show car, but I want it to look nice ya know?
