HI Kim, definitely use a top coat. The top coat is the clear layer that won't mark as easily as the painted layer. It allows easier clean ability and won't get "sticky" like the paint will. Finally, make sure you use a primer like Kilz to block and oils and stains that might be left on your cabinets before applying your finish color.

Hope this helps!!

I've read that the top coat will "yellow" with age, and that you don't really need one. We have recently painted our cabinets and did not put any top coat on.

Does on top coat doors, door frames, and baseboards with a clear to protect it further? No, these coatings are designed to be self sufficient without the use of coatings on top.

No, Not only will doing a topcoat on top of Advance give you no durability gain, it may make touching up harder down the road.
