How you protect pcbs from oxidation?

Wipe on a little solder paste flux. Solders well/better and no corrosion.
Just takes a light amount.

Something else i tried before getting Liquid Tin is Testor's Candy Green lacquer from a model shop. You can solder through it and it leaves you with a board that looks sort of like it has a solder mask on it.

That looks nice. The only thing is that spray enamel takes so darn long to dry! 

Thanks Paul, i don't remember how long it took to dry but it was probably two light coats and then it would be sitting for 'x' number of days until i got back to it anyways. I checked the can of paint that i used  and it is the enamel that head spaz linked to in his post and not lacquer like i said. It was pretty easy to solder through, i think i turned my soldering iron up a bit from where i normally run it.

This picture was taken 4 days after the first one i posted so it was plenty dry before i started soldering. This was the only board i tried this way as i went and bought some Liquid Tin after that. My body revolts when i try to use solvent based spray can products so i've  pretty much got all of them eliminated from my building/decorating process.

take care,
