CJP nail systems have a no wipe LED top coat that can be used on natural nails
The universal one? What do you mean buffing to colour? ThanksI've used the Cuccio UV top coat (not the veneer top coat) and has worked fine for me

It does need buffing to colour coat though if used over gel polish, I use mainly on extensions.
