What you are looking for is called layout fluid, a typical brand name is Dykem, McMaster-Carr
Two 8 FL oz of Dykem Layout Fluid Blue 0 214 | eBay
Hi guys, I'm having a bit of a problem here, I need to buy or to make engineers blue, the stuff you use in scraping, checking out high spots on your surfaces. I spend hours and hours on google, ebay etc, trying to find an online shop who sells the stuff, nothing... Some time ago I've tried to make my own, mixing clear grease and blue chalkpowder, didn't work. Anybody any idea's?
Thanks for the reply Iancem, but layout fluid is a color coating used for scribing fine lines, marking lines where to cut or file. It dryes very fast like the ink in a marker. What I am looking for may not dry out, you put it on a very flat surface (surface plate) and glide the piece you want to make flat over it, any high spots will be stained with some blue, this is where you need to scrape off a little bit of material. Repeat this untill the whole area is coated with blue, then your piece will be flat. But thanks anyway for the reply.
