"Rosin - Based" Fountain Pen Sealant Threadlock Test

In yesterday's post, I had a go making "rosin based" fountain pen thread sealant, letting it cool overnight and leaving you with the thrilling cliffhanger "So, does it work?" Today, I opened the bottle to investigate. Now read on...


Well, the good news is that the rosin sealant had not hardened at room temperature overnight, so I must assume that there is at least the required minimum amount of castor oil in the mix. It's certainly very thick as it is - thicker than shellac, certainly. I tested a tiny amount of the goo on a ballpoint's threads, and the results were encouraging... A picture says a thousand words, as the saying goes. Here's 7 minutes of pictures at 30 frames a second!




I'll finish writing this post, and apply some of the rosin based sealant to the threads of the Jinhao 321 shown in the video - I'll be sure to let you know how it works out in future posts.
