I did a quick Google and also a search on a couple of other forums as well and nothing popped up to solve this problem, so if I'm duplicating what everyone already knows, sorry. In all the years I've been using EPDM sealants, I've never gotten it all over me. This time was different

I got some on my hands and a splooge of it got on my jacket. Don't ask.
I do have naptha in the garage from an old commercial project I ran. Naptha is the solvent listed on the tube.

For those reasons, I completely avoided trying it first.
