MEK doesn't have quite the flash off of acetone and is a stronger solvent. Both of which are desirable properties in this usage. Breathing the vapours or significant and prolonged skin contact is not desirable with either. But then I've used MEK as an emergency lighter fluid before so why would you trust me? (g) (and don't use acetone for that or you'll light your whole face) Work, as always with solvents, in a well ventilated space. MEK also cleans up your still wet epoxy brushes quite well also. It's the primary ingredient in PVC pipe primer and a derivative is the catalyst for gelcoat resin.
If you spill it on your boat you'd best be wiping it up rather soon as the stuff will dissolve about any plastic if left to rest.
