CAUTION: NOT GOOD WITH ALUMINUM
on November 1, 2010
I would not recommend running RP ICE with Aluminum engine or radiators with DISTILLED WATER.
This ONLY applies to DISTILLED WATER with out anti-freeze. RP ICE with distilled water is corrosive and will eat away at your aluminum engine parts.
I ran RP ICE with distilled water combo for max cooling for my track car. What happened was my heater core was corroded and started leaking from corrosion caused by this product.
Also what you will notice is if you get this product on aluminum parts, it will stain the metal white and cannot be wiped off. It also leaves a grey coating inside your radiator and piping.
I would recommend using Redline Water Wetter as an alternative. I get the same results with water wetter and it CAN be used with 100% distilled water with OUT anti freeze.
I am a BIG fan of RP products and PR ICE is the only product from them that i have had problems with.
If you run RP ICE with distilled and ANTI FREEZE, you will be ok. I would still recommend RL Water Wetter
