Here's an even crazier idea:

food coloring powder. super concentrated, no water.


@JasonC SBB I fully expect you to buy the cheapest dot4 available and test the options.

 

But your dye needs to be soluble in something. A dye that is water soluble may not dissolve in oil, and vice versa.

 

The particular ones I use are made to be soluble in alcohol. But that is not necessarily the one you should use. Dry dye powders are the way to go. Just have to be smart about it.

Many different choices on ebay. All types, all colors. If not there, then there are plenty of places elsewhere on the web. Liquid dyes are a ripoff, you're paying for dilution.

 

I don't see why this is so hard. Just do what I do: run the brake fluid until it's black. Then, while bleeding, once you see black stop coming out, you know it's all good. No dyes needed. When the new fluid turns black again, you know it's time for another flush.

 

^ That's what I did... until I boiled my 8 month old, 4 track day old Motul and bled it... and the damn color was clear like new.

 

"Glycol Ethers for Inks"

http://msdssearch.dow.com/PublishedL...romPage=GetDoc

"When used in ball point and felt tip pen inks, glycol ethers allow the free flow of resin pigment and dye preventing clogging or drying out. The result is good flow, leveling and print detail. The higher evaporation rate of DOWANOL™ PM, PnP, PnB and Butyl CELLOSOLVE™ products provides faster drying in writing pen ink applications.'

Hmm, does this mean you can just take some ink out of a ball point pen?

 

hi,
did anyone on here try using the Kingscote stuff? or powder dye?
any feedback?
thanks
