Homebrew PCBs

Well, I'm new enough to this etching process, that I wish to ask a question.. First, I'll say I am very happy to see a nicely etched board, having good solid copper carriers..  So now what is the purpose of tinning.?  Can someone give me a quick answer.  Thanks.

  I use a product called Tinnit that comes as two powders you mix with water and heat. I've been eying a bottle of liquid tinning solution that doesn't require mixing which I think I'll try once I use this stuff up.
