added 15 drops of my not-so-good MEKP to 10cc of gelcoat. again it wasn't getting noticeably viscous after a few minutes, so I just left the batch without applying it: something that's not overly painful with these microbatches. it was hard after I went to check maybe half an hour later, except it was still tacky on the surface. but my Facebook friend Matt says that's normal for gelcoat, it will still leave a fingerprint a day later. so I guess I'm good with about 5 times the normal amount of hardener. gonna try and finish the job tomorrow, then re-fill the spa and see if it holds water.
