@Outlawz:
Like I said, if Luffy can figure it out, Lucci can, it may be OP but many basic rules still apply, like Sand can't disolve when wet. Lucci would most likely know Crocs devil fruit, so he could easily figure out the weakness.
Well, it wouldn' be advisable to figure it out the way Luffy did because he would be dead. Also, I'm saying how would he know. It seems basic but this is after the fact. Right now we don't know Aokiji's weakness, but when it's revealed, I bet everyone would say that it seems like everyone would know it. But these things aren't widely known. A common person doesn't know much about Devil Fruits and for someone such as Crocodile, a member of the Shichibukai, if his secret was known, then it was kept hush hush by the Government.
I doubt Crocodile is fast enough to land too many fatal blows on Lucci, water, blood, saliva, urine, any kind of liquid will make sand stick, if he sticks his fingers in his mouth and licks them around, BOOM shigan and you're dead.
I was saying inside of the storm. If you are inside, then everyhitng could attack you from anywhere. Also, sure, liquid nullifies it but it seems like it's not that easy. Remember, Luffy ate Crocodile. It's pretty wet in people's mouths but apparently that wasn't enough. So that wouldn't work. Someone has to be drenched.
Even if he does get caught in a sand storm, he can just keep evading untill the storm dies down, from what I can remember, Lucci's defensive abbilitys and will to live are very impressive.
However, evading inside of a storm seems impossible. That Sables Pesado was everywhere and looked pretty impossible to dodge. If Crocodile could make a storm like that, or like when he did the Ground Secco then Lucci wouldn't know what to dodge or where. Sure, he has a strong defensive capabilities but if he gets a body part dehydrated that won't be good.
