Safe to spray clear coat after several weeks of the paint drying on painted TE?

Hey guys and gals,

I painted my TE a few weeks ago and put a nice clear coat of sealer over it back then. However, I am starting to feel like maybe I should put one more over it, I’ve noticed just a TAD bit of wear where my fore arm rests on the right side of the stick. Is it safe to spray after all this time? Or would I need to sand/paint/seal all over again? Thanks!
