Nutsville, interesting what you say about using thinners like As Good As New. I have tried this, as well as an Orly one I got from Amazon (better value as bigger bottle and I used an LD dropper to add it to the polish). I have not had much success sadly. It definitely thinned the polish (using a lot more than the recommended 2-3 drops - like you, I needed a whole pipette full at least). But manicures using the thinned stuff take forever to dry. I am sure it would take ages without thinning as gloopy polish is slow to dry of course, but you would think the thinned polish would dry quickly. Any more tips, apart from leaving it an hour before using, which I have not tried?
You definitely need more than a few drops of As Good As New. I tend to do my manicures in the evening usually after a bath or dinner and the heatings on and the flat is at it's warmest or during the summer I switch to the middle of the day again when the flat is warm. I did struggle for a while and tried with out success Miracle Drops which still took an age to dry, then the Miracle Spray was launched and because it sprays on cold all of a sudden my polish is drying an awful lot quicker. I have about 3 new tins as I don't want to ever run out.
