A friend of mine (an excellent spray painter for cars etc.) sprayed his dish, not telling me.
After 2 month he had no reception. Lucky for him, he had a LNB (California) with a LED visible outside, to indicate power at the LNB. That LED was off (he looked at night time from ground - ususlly easily visible). Next day he phoned me and he sounded very exited. - We have a biiig short, the front cover of the LNB melted away and I have no picture - . Not knowing what to say, I visited him.
But when I saw that shiny, in dark brown (to match the face briks) spotless spraypainted dish, I knew what happened. The LNB was virtually fried & cooked.
LNB was replaced but first -
- dish down, water grinding paper 600 (or whatever he called it) and the paint received after some effort, a matt finish. That was 6 Years back. Replaced LNB still working.
