    rex362 paint clear and drive

    Best to get re-builders recommendation on that ...


    imo 100% synthetic ,stands up to the heat better.
    brand ? your choice but I like Amsoil or Redline

    and also note : it a good time to flush the lines and cooling section in the radiator
    of old stuff before filling up fresh
