I have to put my hands up and admit that I was a bit quick to judge the Color Club top coat. It actually is a really good topcoat. I painted these nails last night and today - no sheet marks. Sorry Color Club, my bad!
Thank you all so much for your top coat recommendations. It seems that Glisten and Glow's HK Girl topcoat was by far the most popular suggestion so I think I need to get my hands on a bottle on that fact alone! Another one that stood out was Revlon and since I can easily dash in to Superdrug and pick up a bottle any time, that's exactly what I did. I haven't had the opportunity to try it yet but it's very... pungent. I hope that means there are some super strong drying chemicals in there!
For this nail art, I used a base of Essie Good as Gold with a coat of Essence Better Than Gel Nails Fast Dry Top Sealer.
When that was dry, I placed on the Striping Tape to mark off where I wanted the foil shade to show through, then painted over it with Barry M Guava. I removed the striping tape immediately, while Guava was still wet.
On my accent fingers, I used two coats of Sally Hansen Big Money over Essie Good as Gold.
It's all topped off with two coats of Color Club Top Coat.
