Mayhems - Coolant Dye - Original Series - Intense Colour, 15 ml - Cosmic Nebula Indigo, MD15MLIN

This product it advertised to react under some elements, those including like know UV Light or Blacklight. Unfortunate this product or its damage or its some other chemical. I have tested this product under a black bulb but have cero reaction still the same color as before with no changes. I also order 2 strips UV led light via amazon with UV light and the result was worse than the Blacklight. So, I came to the conclusion that the product its defective. I request from this seller a return because its defective and the cost of send it back its above the price of the product. Hope this seller its more reasonable. A real reaction with UV Dye for auto coolant.

Well, it does what it says. It dyes your coolant orange. It looks good in my loop, so what else can I ask for?

Had great color at first, but left residue on all my tubing and blocks and discolored quickly.Providing images of my GTX 1080's block after the fact.Everything was cleaned and all blocks are cleared so it did not leave a lasting effect.

Easy to use. Great color.

Color can change purple tint . Not good

Pictures don’t do this product justice. If you use it make sure you have stuff to clean up any excess because this stuff GLOWS BRIGHT

I built a pc with hardline tubing in the watercooling loops. This dye came up a very strong and good shade of blue. Very pleased with the resulting visual effect.

Bought this to add colour to my custom loop, and the added bonus of been able to get the exact colour you want.

good item and very deep colour and pc run cooler
