I thought there was an glue like stuff that you put all over the board... Or even an waterproof box for the board?

Yeah, there's a 'grease' that you can put on your board to protect it (i saw that on a swimming pool robot control board) or you just can buy a IPX.X box that's waterproof.

Use epoxy or polyurethane. Comes in cans with catalyst in 2 parts. Also try silicone rubber, which peels off. Good luck!

Silicone sealant, like you'd put around a window frame) is good for a component or two. I prefer the 'Neutral' colour. For a whole board there are sprays or dips, usually polyurethane.

Servisol Plastic Seal for example. Available from Maplin in UK.

Reference conformal coating. MG Chemicals has a clear polymer spray for circuit boards which works great. You can find it at any electronic component supplier (Digi-Key or Mouser for example).

Thank you all for your replies pointed me in the right direction like always. I did a little research and found some additional information/suggestions on epoxies and silicones. On the note of epoxies be careful with ones that are formulated to bond to metal as they may contain metal fragments; clear is generally a safe bet. As for silicones natural (or neutral was one of these two..) set should be used as the ones that arent excrete an acid as they set.
