Damn things stuck!!!!

[GetANet]

I recently got a newer boat and this one has the springfield style seat posts and i have one that was practically impossible to remove. I did finally get it out but only after i used every ounce of energy i had and almost knocked myself out with it when it came free! My question is what do you use to prevent this from happening? I thought maybe grease or silicone spray or armor all on the end and the plastic sleeve on the base? Hope somebody has a good answer for this one!
Thanks in advance for your help!!!!
