Hello! I purchased a Gothic gold Waterman 52 1/2V from Ebay some time back. Upon opening the package, I was greeted with a strong smell similar to paint thinner. I sighed and immediately checked the section and barrel. Sure enough, I saw a clear ring of some sort of sealant between the two. The smell has not dissipated much a few months later, and I am still unsure whether it is the sealant or someone has tried to soak the section in a solvent. The hard rubber still has its black sheen, so it couldn't have been something that would cause it to go dull.
After reading a bit on this forum and some other pen restoration websites, I tried carefully heating the barrel with a hairdryer (I am fairly new to fountain pens and do not yet have a heat gun). The section still wouldn't pull out of the barrel. I do not know whether I am not applying enough heat or whether the sealant has a higher melting temp than the hard rubber.
Anyone have other ideas for what the sealant could be or what to do? Should I try again with heat and not be so skittish this time? Just send it to a professional?
