There are two kinds of marking blue: There is a grease type like Prussian blue that is used for scraping and precision fitting that will transfer from one part to the next. Apparently Prussian blue is messy & very hard to clean up. I suspect there may be better options. I've never used Prussian blue, but have a home brew equivalent which is lamp black mixed with vaseline. The other kind of marking blue is more like what you would get with a marking pen, i.e. a thin dark material you can easily see a scribe mark in. A wide tip black marking pen works fine for this, and is easy to clean up with alcohol. I've used brush-on Dykem "layout fluid", but it tends to go on thick, it can chip, and it's harder to remove than a marker. If you have a large area you need to cover, you can get the best of both worlds by using a Dykem felt tip applicator, which is like a marker, but lays down a 1/2" wide stripe. It goes on thinner than the brush on stuff, so it dries faster and is less likely to chip. It's still harder to remove than marker. Doug White |

Is it happy to stay on the shelf for extended periods? I've had good luck with them so far. The bottles of brush on stuff tend to go bad long before a home shop can use one up. The applicator bottles are much smaller, and I suspect the ratio of time to use them up & time to gunk up is much closer to one. A 2 oz. applicator is ~$4, where a 4 oz. bottle is ~$5, so it isn't cheaper to buy the applicators by volume. On the other hand, if it goes bad before you can use up half a bottle, the applicator is cheaper. The other big plus is that you can't spill an applicator bottle. I've seen more than one shop where somebody knocked over a Dykem bottle. It makes a very big mess. Doug White |
