what type of antifreeze and paint code for rms?

My 928 is a 1981 with phone dial rims. I am planning to refinish the rims and need the paint code. I'm also changing the radiator and hoses, so I'm wondering about the proper antifreeze. Thanks for helping

My mechanic uses DexCool (the orange stuff) in my 928s.

I can't say if this is accurate for the phone dial wheels, but from what I've read in general newer Porsche wheels are painted Porsche GT Silver code M7Z.

thanks Rich
