Is cobalt drier better than Japan drier? I struggle with Mississippi humidity when finishing/refinishing gunstocks and have been using Japan drier with some success. Just wondering if anyone here knows if cobalt drier is better. Thanks.

I don't know, but Japan drier works for me even in humid conditions. You might call a good art supply store (or one of the internet suppliers of professional artists' materials) and ask them.

John,
We use both Cobalt and combination dryers in the printing industry for much the same reasons. You are probably going to discover that you get a crusty film on the top of your finish of choice with cobalt drier, since it works with contact with atmosphere, and humidity level changes the reaction. So does exposure to UV light, if I'm not mistaken.
If Japan is working, stick with it, and try to perfect your technique.
Best,
Ted

In my limited experience I've found that less is more with japan drier. Using it in french polish I realzed that if too much is added everything gets clumpy and drying is inhibited. Just a couple drops in small batches is just right.

Have you tried a dry box? I made mine out of plywood with a light fixture at the bottom. I ust two thermometers (top and bottom) and keep the temp at 85 degrees for about an hout. This helps on humimd days for me.

John,
General rule of thumb.
Japan dryer is to be used in linseed oil based finish.
Cobalt dryer for tung oil based finish.

Thanks guys. I've been doing stocks for about 35 years now, so I've tried just about everything out there, except cobalt drier; just wondering how it worked for you. Never gotten around to building a dry box. Japan drier has helped a lot, but I've found it's just best to wait until October to start, and don't do any more after May.
