Working in the railway area (passenger information systems) we have to coat all our electronic devices against moisture and (often conductive) dust. I had a look at what we use and if you google for "sl1360 conformal coating" and maybe "Lackwerke Peters" you should find the stuff (and maybe even some source in your area) very easily.

The coating can be brushed and sprayed and is available in different colours but we use mostly the transparent variant. While wet it will fluoresce in UV to check for even coating. You can solder thru it (if really necessary - it will get brown and stink!) but I don't know whether there is a solvent to remove it completely (ask the manufacturer?).
