just found this - am still looking,.......
"Exceeding an 80 percent concentration of antifreeze in the coolant can cause silicate gelling. The silicate corrosion inhibiting additives that are found in most "aluminum-safe" antifreezes can drop out of suspension, forming a gel or greenish goo that clogs the radiator and reduces heat transfer.

and this...
"If you are planning on doing that, then make sure you thoroughly flush the DexCool out, and replace the thermostat before you install the green etylene glycol antifreeze. Problems have been reported when the two different types of antifreeze have mixed, including "gelling" which causes blockages in the cooling system, and a possible breakdown in the protection package that the antifreeze has to offer due to contamination from the other antifreeze, which offers a different protection package to the engine and cooling system. Here is a link to some more info on switching from DexCool to ethylene glycol based coolant. Antifreeze: Red or Green?"

Cos it seemed a good place to put it at the time cos it int specific to anywhere else.
I've not heard of it before an a bloke at work asked me cos his new to him car has red antifreeze in it and he wonted to know if it was ok to top it up with green antifreeze cos he'd heard about this gelling malarky.
Any how it seems from yer links that as long as its ethyl glycol it shunt matter wot colour it is, the problem is finding out wots in it to start with.
