Anyone Try "Touch-Up" a Wrinkle Paint Item?

I have not yet installed the Formula S black wrinkle finished valve covers. But moving them around since painting, I have some minor blemishes. Don't know if paint got bumped, paint flaked off, or maybe it's just dirt/soil. Anyhow, for now and future reference, can this type of specialty paint be touched-up the same as other finishes, or will that mess up the wrinkle finish worse? Thank you.
