A bit of a shot in the dark here but worth a try!
I’ve bought a car amp but I’m going to use it on a boat. It seems that ‘marine’ amps are basically car amps but with a conformal coating on the board – so I was thinking of spraying my own as I can get a small bottle for £10.
So, has anyone sprayed their own boards and if so was it easy enough and is there anything on an amp board that I should mask off first?
