Forum:Devine Wrathing Blue-Eyes Shining

If I use Blue-Eyes Shining's negating effect against a sakuretsu armor or something and the opponent activates Divine Wrath, can I use shining's effect again and negate that? How about if the opponent uses divine wrath when i summon shining and its continous effect activates (the one with gaining 300 atk for each dragon in the graveyard)?
