Thank you! I am going to try that next time. I get bored with my colors after one week too and I would like to take advantage of my regular polishes without them chipping off. I guess I will have to make sure the regular polish is nice and dry first before applying the Gelish topcoat.
Yes! Just use a buffer block or file and file off the layer of top it off - it doesn't have to be all off, but you want a non-shiny surface. Put on your regular np. Let it dry COMPLETELY. Put on top it off again and cure!
