I have to replace my Pentair heater HMI / control board. The control board came with an anti-corrosive coating as illustrated by the glossy finish, but the little display board didn't. This is what went out on my unit. Is it safe to apply MG Chemicals 419 Conformal Coating to the little display board? Since this unit sits outside, I don't want to install the new expensive part and have it corrode again in several years. I also don't want to damage the unit.


Thank you
