What you really need is an electroless Tin plating solution.  You
can do a search on "electroless tin" and you should get some hits, 
both of commercially available plating solutions, and instructions
on how you can make your own.  One of the better discussions is
here (Note the post by Ted Mooney):

Back when I was young and immortal [1], I used one of the Cyanide
based Tin plating solutions, and it worked quite well.  However,
now that I'm older and more mortal, I refuse to use Cyanide in a
home lab.

[2] Hey, I said "immortal", not "immoral"!  :*)
