What are you using?

For all you racers out there running aluminum radiators - what additive are you putting in your radiator to lubricate and inhibit rust ?

Your not suppose to use any radiator additives or antifreeze if your racing at the track/drag strip, it makes it too hard to clean up, I do use Purple Ice in my Street/Strip cars with aluminum radiators though...

I use water wetter.Works well for the roundy round guys.
