Hi there, just a quick question, I was having a play with my nails yesterday, and had put out way to much monomer into my dappen dish, I put the lidon as I have 2 new clients coming tonight for full sets of P&W, the lid of the dappen dish isn't airtight...so...I know that with some liquids when they are evaporating can leave a stronger concentrate of what it originaly was IYKWIM, is this the same with monomer, should I dispose of it, wouldn't want to use it if it wasn't going to do the job properly.........bit of a long winded ? for a quick question lol....help appreciated:hug:
