Hi I am not familiar to conformal coating process and I would like some advice of using or not conformal coating in this specific application. The board will located outside and should work properly for several years, but will be enclosed inside a WEATHERPROOF and DUST-TIGHT box, this condition is enough for not use conformal coating ? Thanks for any advice.
