The Fatadder's Modern Workbench

The trick with Railmatch jars is to keep the interface twixt jar rim and cap thread completely free of paint. Before you replace the cap, thoroughly clean the inside of the cap and the rim and thread of the glass jar so that you can see no trace whatsoever of paint, wet or dry. If you have some, apply a little Vaseline to the jar thread before replacing the cap, but this is not absolutely necessary. Saves time and hassle next time you come to use it.

Thanks will give that a try, unfortunately the lid partially shattered when trying to open the jar, so I’m not too sure how well it will last now.  That said the paint is getting on for 20 years old now (even if it’s only been used twice in that time)

I had the same problem. One jar i never was able to open, having virtually destroyed the lid in a vice, the very top remained stuck fast! Mick's advice shall be followed from now on for me.
