many years ago, I did re-flow soldering. Put the board in peanut oil and heated it. Added some solder. Wiped and then re-flowed it. I haven't tried the method with the lead free temp solder yet. An oily residue might be objectionable, though.

Eddie,
I'm new to etching too, so I am going to ask a naive question.
The link you provided looks like the tin plating takes place PRIOR to etching.
I thought the tin plating took place AFTER etching.
I believe Steven's solution of using rosin flux and alcohol is meant to be used after the etching process(I think).
I'm a little confused with the timing. When is tinning meant to take place?
Thanks.
