Has anyone tried this with blue highlighters? I was thinking that that might not work as well, green/yellow highlighters always seem to be the brightest colored ones you can get.

Well a good test is you go to your store and put some ink on a sheet of paper.
You then try to convince the lady (it usually is a woman) at the casher to let you use her black light detector for conterfeited money -> you will know instantly whiwh marker reacts the most ;)

Unfortunately you will also notice that the brighter ones are yellows, greens and some orange/pink ones.
The blue ones are almost non reactive :(

they glow really well! Nice find!

The blue ones seem to be trickier to find, but they're out there. There must be something expensive about the blue UV chemical.

I've got a blue BIC right here, I might test it today.

I just bought a blue marker, and a four-pack with yellow, pink, orange and green. I'm going to try out the blue and see if that works. If not, I think I'll go for the orange, I'm pretty sure that that would glow nicely. Anyways, I'll post my results in here later tonight.

Im still testing this and have Not added it to my system yet.
FYI

I tried out all the colors I bought, and the only ones that would really be worth using are green and yellow, the two colors that I liked the least. Blue hardly glowed at all, and orange was mediocre, certainly nothing special. I think that I'll just order some blue UV dye somewhere online instead, I doubt I can figure a way to make that highlighter fluid glow any brighter.

Bought some UV Dye from Checker auto parts last night for $4 and I got 2 containers for that price. The stuff is Brownish/red like the Tracer Line and it glows very strong with just 2 or 3 drops. I asked the girl there and she said it has been on the shelf for a while, but it did not loose it kick.

So I will be using this for now.

Wha?
 

Hmm, it's green with-out UV light? What colour is it under UV?
I'm looking for bright Blue. Could you or anyone point me in
the right direction?

I just bought the Bic Brite Liner 5-pack to play with. Too bad
the blue sukz.

Blue uv dye, from my understanding does not last as long as the yellow/green. Dtekcustoms.com does have the blue you search for.

I have tested the blue from Dtec but really it was nothing special. Some drops (as said in their site) do completely nothing. I had to put enough to just see some color. Also with 3 uv cold cathodes the liquid wasnt bright at all. I have also tested 3 more uv blue dyes from watercooling.de and from pclincs.co.uk but neither they worked...
I think i will try this highlighter trick.

The best dye I have come accross is the UV dye for radiator testing from Checker Auto parts store.

Also the highlighter dye is very strong but maybe to strong for pump drive. Im guessing here and have no facts to stand by. Its just when I smell the UV mixture from highlighter, it smells strong. Hmmmmmmm.

And when I smell the dye from Checkers, nothing.

I made a order from some dye from another company and waiting on them.

What color is the dye you picked up at Checker? I'd like to go with either blue, or orange if I can. Green is rather boring IMO.

heh!
 

Unless i'm as Denso as my HC..... I still don't know what colour
you're getting under UV.... Heh!

If you are looking for something to glow blue, you guys might want to try Rit Whitener and Brightener... you can find it with the other laundry detergents in most grocery stores (I found some at K-mart also). The stuff definately glows blue, but it's not as bright as some of the other UV dyes (like hilighter or leak detector dyes). I don't know if it'd mess up your pump, but i'd assume it wouldn't be that great for it, especially since you need a decent concentration to make it bright.

I am using it, instead, to paint my clear fans... I mix the Rit with a clear coat paint (nothing with UV protection) and paint the fans... then they glow bright under UV, but are clear the rest of the time. Sorry, no digicam to show the pix..

:(

The dye from checker is brown/red in a bottle. Its the only thing they have thats UV for radiators. It glows Yellow/green under UV and looks green during day.

Favorite?
 

Ahh, ok thanks for that. :)

So, how 'bout which one you prefer to use now and why?
Between the: cut yellow hi-liter, and the checker UV dye.

You can find blue uv dye here to:

WANG:

I prefer the checker uv dye b/c it is safe.
Im not sure if the highlighter dye will have a effect on magnet drive shaft.
Plus checker uv dye is so strong, the strongest I have seen yet.

Thanx for the link Sproket, and for sharing your info.

Welcome to Procooling Wang!

why would dye harm your pump?? :shrug: its just dye lol

OMIGOD! IT DYED MY SHAFT YELLOW!!!! :drool: :p

OMIGOD! IT DYED MY SHAFT YELLOW!!!!

Hahaha........

The Highlighter dye is very strong almost, chemically. It will clean copper to a very good shine. Now what happens to other metals is my concern.

So far my test have revealed that nothing is bothered by this highlighter dye.

Clean it only, or does it corrode it?
And a highlighter does glow on UV? Nice find! :)

Well I just took the plunge and rebuilt my system with a AquaCoil II Rad and used my home made Highlighter UV dye and WOW, nice bright green and all is good Now.

I put an extra mag drive shaft into solution for testing and it did not bother it, also some copper pennies. test went well for a week. Now Im using it in system.

As much as people have used all sorts of different dye's and such, NOTHING I have seen can compare with Dye Lite. (the original stuff I used in DH3.. you know the thing that started the whole "glowing coolant" deal on the web? ;)

hehehe you can get it at most automotive places because its used for coolant leak detection. Its far more bright than any highlighter concentration I have seen, same with woolite.
