attempted another 100ml batch of gel-coat. that from yesterday (or was it the day before?) had finally hardened in the mixing container but still had a tacky surface. this time, realizing the clarity of the resin indicated I had mostly styrene and not polyester, I shook the can vigorously to mix it. then I added 4 drops of MEKP instead of the 3 I had added to the previous batch.

it wasn't good enough. still hadn't gotten any more viscous after 10 minutes, so I added a few more drops of the hardener. 10 minutes later and it was still only semi-viscous. I'm about to give up. I guess the MEKP broke down over the 8 months it was sitting in storage.
