i bought some engineers blue that came in a small tin. It's like a cream and oh boy what a messy product. End up with blue everywhere.

Are there alternatives i.e. A pen or spray paint or both

For layout and marking out I use Dykem but for checking fit or scraping I've never used anything other than Stuarts Engineers blue. I do buy mine in the tube now (sold by most suppliers eg Arc, RDG) as I find the tube more convenient.

This has been covered in a scraping thread over the last week or so.

I think this is the thread Chris refers to.

Indeed, you have the opposite problem to Mr Tinsley!

I can't believe this, within the same week, two posters have confused engineers blue for different purposes!

The stuff you want is layout ink, not the marking paste, that's used to find contact points on metal and scraping.

You can get it in a bottle or spray. Failing that a whiteboard marker will do for most jobs.

Don't throw it out though, it's still useful! Just not for what you want cheeky

Gunsmiths traditionally use a smoke lamp to deposit a very thin layer of carbon on the surface to be checked. It's nothing more than a small paraffin lamp with the wick turned up to give a smoky flame, although a candle will do.

In an emergency you can dilute Marking Blue with Meths to make a Layout Blue substitute. I don't recommend it. The paste doesn't dissolve without mechanical effort, it's messy (you're liable to end up looking like a Smurf), and when applied to metal the coverage isn't as good as the real thing. You can make a similar potion with the ink from lots of cheap blue biros. A lot of trouble for a moderate result.

I've used various types of felt-tip markers with mixed success. So far nothing has worked as well as commercial Layout Blue. Judging by the number of Health and Safety warnings on my bottle of Dykem, there's more to making a good blue than mixing dye and alcohol.

I've never tried Copper Sulphate solution which the old guys swore by and at. I believe it's only good for marking steel, not other metals.

Felt tip pen, black or blue

Which make Mick? I'm using a Berol at the moment. It's OK but not as good as an unbranded I got from a Pound shop. Of course the Pound Shop no longer sells them.

I've used Pilot brand jumbo markers for many years, far more convenient than layout fluid. You have a choice of blue, black, red or green.

You can get refill ink for these if required as well.

As someone mentioned, there is a spray can layout blue dye called Dykem that is widely available. Google Dykem layout fluid and you should find it locally.

For small jobs I use a Pentel N60, Sharpie for really small items, Edding markers also work reasonably well, the only thing I find with markers is that if using paraffin as a cutting fluid on aluminium the colour of the marker soon comes off.

For a more durable layout I just use a bottle of "layout fluid" bought many years ago from one of the ME suppliers and a cheap small artists brush to apply

Rocol do a spray available from MSC in the UK

I have used permanent markers quite a lot but I coughed up for a bottle of Dykem, it is so much more durable and takes a very crisp line. It is the blue of choice for anything that is going to be handled a bit or have lots of work done on it. Still use marker pen for a quick simple job so I think it is a horses for courses choice. Dykem may seem a bit dear but it is a very good product, it is superior to the blue I used as an apprentice which could be a bit thick and not take such a fine line. As has been mentioned Prussian Blue artists oil paint is not bad for checking surfaces and fits but there is always the blue finger to be dealt with with all fitting blue. The toolmakers on the spotting presses used red lead on the dies, always amazed me that you could see your face in the cast iron after they had polished it. As is the way in a factory they were called "pig iron polishers" the millwrights were called hammers and spanners we were sparkys and so on.

Good to know, thanks!

I have the same trouble with aluminium not taking the sharpie ink well after a judicious amount of WD40.
