Mercury's Medium CA makes a great top coat for your wooden pens. Depending on
the number of coats applied and how highly polished you make it, it can provide a somewhat
natural to a glass-like feel for your finished work. Of course, it is
also excellent for gluing in the brass tubes. Mercury Adhesives
are manufactures in the USA, in Atlanta, GA. It is a medical
grade CA that is highly concentrated and 99.9% pure. For finishing pens,
just a drop or two is all that is needed for each coat. Reduced fumes are also a feature of Mercury CA. Another unique feature with the Mercury CA range is the clog free nozzles which are on all the 2oz CA bottles. There are three sealing points within the cap, including a steel pin to help keep the tip clear & open. If CA does build up on the tip or cap, just soak it in acetone for little while. These bottles can be refilled and reused many times.
The jumbo 8oz bottles of Mercury CA
have a screw top and are ideal to use as a refill to top up the 2oz bottles.
You can also purchase cheap squeeze
bottles at a hobby/craft shop.
