The last few days, I've been trying my hand at making some of this elusive "rosin based" sealant that sounds so handy. It's not something I've seen for sale domestically, or, in truth, at all, ever! I've come across various clues about consistency, proportion of rosin to castor oil, and so on, but with no experience of the stuff, I'm not sure if I'm getting close or way off the right track.
Today's test threw up a lot more questions than answers, so I'd like to ask anyone who's got ahold of this stuff how this DIY mix differs from theirs!
