I have a fair few OPI polishes and I recently got Lincoln Park after dark,however its quite sticky and hard to apply- with the other OPIs they go on my nails smoothly.
I was wondering if anyone else has had this problem?
I know what you're talking about; mine does that too. Try using OPIs nail laquer thinner - or another brand. I pick mine up at Ulta. Don't use nail polish remover as this is not laquer thinner. It will dull your polish.
I agree with the previous suggestions. Also, clean the neck of the bottle and the inside of the cap. If there is excessive buildup of dried polish, the bottle won't close completely and air can get in. That will make your polish turn goopy for sure.
