I use pre-mixed Tectaloy in 3 of my Skylines without issue. The GTR for a decade.
Both stock and alli radiators. R32 GTR, R32 4 Door, R34 GTT and a Liberty
If you have had an issue it was already corroded, or you have mixed red/green coolant without a proper flush.
If you add water make sure it's distilled as mentioned above.
