Thank you all, great experiences and advice, specially PentaxJax for his support.
It's Been more than 24 hours is in the bag with disecant and Phase II is ON, I bought cat litter of pure silica gel and made my own silica bags with tea bags, put one inside the battery hole, one little inside the lens mount and left open all main doors, put six more around and the others I had sorrouding the whole camera, and the glasses of rice nerby in another space but in the same bag. So this is it, I couldnt put more disecant in the play, in 24 hours I will try to turn it ON. I'm in the edge, i don't know what I will do if it doesnt start... Sure, i would love to buy a K5 II but my finances are really tight at this moment, awful I would say.
Wish me luck
