Layout blue

[Kram]

I have been using marker pens, not seen the proper stuff for sale, though amazon has it at £30 a small bottle. My fingers always turn blue and make a mess of the part.
Youtube suggests making some up using ethanol, dye and shellac to allow it to dry hard and wont rub off easily without solvent. Anyone tried or what do you use?

The blue will go bad after awhile, I have red that is good and bought it in 1982. Recently found out, thin it with drug store alcohol.

Spectracolor and it’s associated remover for me

And I'll bet you didn't pay the high price they are asking for it now. Last time I purchased Dykem it only cost $2.29 a bottle.

I've got a litre of Rocol layout blue, it's ancient but still okay. I've not got through my dykem yet. It lasts ages

I have an antique bottle of the stuff. It's not going to go off! I think it might be "spectral blue" but it is definitely cut with methylated spirits.

No issues with dykem.

Apart from the mess...

Spotting blue is a different animal. Layout blue is preferably very quick-drying but spotting blue has to transfer so quick-drying is not a desirable feature.

I have heard, well the old way was a tube of Prussian blue oil paint from an art suppliers, thinned with spirits. Probably the cheapest way of making it ?

Scraping uses the sticky greasy paste I believe, not the drying layout stuff.

Theres a few videos on YT comparing Dykem with others. I notice Dykem is a bit light on the dye. Found this comparison

I feel £14 for 100ml is a bit too much if its not that much better.

Youtube has convinced me to try shellac and dye, shellac is quite cheap and should be here in a few days. Without the shellac it will rub off and be no better than marker pens.

Evaporation rates, Acetone is about twice as quick as MEK, which is about twice as quick as ethanol. I have plenty of MEK to use up so will try that first.

One of these in basket too, for holes

This guy shows off a super-wide marker pen in one of his videos. Here at 4:52 I dunno if you can get it over here though. BTW check out his other videos this guy is a mine of info on panel shaping.
