Be careful with that Armor-All. As it is a super-efficient surfactant reducing the frictional bonds between your drysuit and the surrounding water column, you could go plummeting right down to the bottom and really damage the coral, wreck, or whatever else you slam down on.
It's just like why people have to avoid sinking ships - it's not the suction that drags people down - it's the reduced friction of the air bubbles escaping the sinking hull - people fall through the air/water mixture and have just enough time to think, "Oh s" and discover that they're at 200', and that's just for starters.
So be careful.
