I've tried Essie, Sally Hansen, OPI, Seche Vite, some better than others but I saw this recommended on a nail blog, bought it and it is FAB.
It's called Glisten and Glow HK Girl topcoat. For me, it is as shiny and fast-drying as Seche Vite, but without the shrinkage and peelage issues. It goes on nice and thin, seems to have protected against chips (did nails 4 days ago and only now seeing some, normally my nails chip within minutes hours) and makes polish look like gel nails. Absolutely love it. Different things work for different people but for me this is the best!
Promise I'm not on commission 
I got mine from Rainbow Connection online shop, fast postage and good packaging :)
