Back when I was in the Navy you could order cotton swabs with a 6" wood handle and the swab part on one end. These were generally used for cleaning electrical contacts and to get into hard to reach places.
I also found them indispensible for both spot application and removal of paint.
Any idea where these little gems can be found in the civilian world?
Hello
You could try electronics shops as I think they are still used to clean VCR magnetic heads.There are other ones used to clean computer parts ( mainly keyboards) but as far as I know they are made of foam and not of cotton. A solution could be a Radio Shack shop ( I live in France and Tandy shops disappeared long ago, I don’t even know if you still have them, but this was the kind of shop I wanted to point anyway)
Now, in the purpose of spot application of paint in modelling world, a much better choice would be microbrushes.
Try medical supply websites. They’re used for “pap smears” of the… ahem… anal canal. Seriously, folks. Probably called “Cotton-tipped applicators”. These have a much bigger cotton tip than the ones at Radio Shack.
