Is this H2O2 similar to the (if I am remembering correctly . . an issue these days) Z-stoff/T-stoff that was used for the ME-163? The description of the corrosive nature of the pure hydrogen sounded very similar to the catalyst (I think it was the Z-stoff) from that aircraft.
Very NASTY chemicals indeed! Improperly handled and you have large explosions. Or melting flesh
I got rid of the Snorkle mod which was screwing up my ship from behaving correctly (except for the Starting Career with a Type XXIII . . left that active). I was disappointed the H2O2 could not be refilled. But knowing that now . . . it does seem to be best used in small spurts. Attack positioning . . . or possibly running away.
