Looks like their opaque isn't what I'm looking for unfortunately.
Maintenance
As with all custom loop water-cooling, continual maintenance and daily inspection is required. If you intend to “fill your loop and forget it”, we STRONGLY recommend NOT using True Opaque. True Opaque will need to be replaced every 6 months or sooner, depending on the complexity and conditions of your loop. This will be required to maintain the aesthetic appeal of your loop.
Warnings/Cautions
Compatibility
Use of this product with aluminum components (such as aluminum constructed radiators) is STRONGLY DISCOURAGED and will void the fluid warranty. PrimoChill will not support or replace fluids used with an aluminum radiator.
Do not mix ANY additional additives, coolants or silver coils with Opaque True. This will change the formulation of Opaque True which can cause the fluid to solidify or break apart.
Anyone out there water cool with opaque and petg???
