I would recommend getting vinyl letters rather than painting again

I think the big argument against vinyl numbers is that they're thick
enough to trip the boundary layer and mess up the laminar flow.
Moffat mentions this a couple of times in "Winning II", for example.

Actually I think you will find that in theory that sounds good, but
most people will not be able to paint the numbers any thinner that you
can get vinyl and have the numbers look nice at all.

When you are losing contests by 0.01% maybe it is time to paint.
