If the humidity down there is anything like we have had up here the last two months you have zero show of air drying a skin, it will putrefy or get blown.
Search on here , there is a few threads on preserving/tanning skins.....at an absolute minimum you will have to salt the hell out of it with the weather we have been having.
Baking soda and kero works to dry and preserve but doesnt actually turn it into "leather" as such...if you get it wet again it will go rotten.
