MEKP with vinyl res?

Mini-sims project is almost finished but I forgot to order MEKP with my vinyl resin.  Can I use over the counter stuff or do I have to match it to my resin?

Over the counter should work fine

Over the counter will work BUT, will allow the vinylester to foam up more.  There are special MEKP’s made to help combat this problem so you might want to ask your supplier first.
