Same thing happend to me years ago thank god it was a older small lowrance, I had to use mineral spirits or wax and grease remover cant remember on the grey plastic case and the screen I used some windex or a different brand glass cleaner took it right off, Test on a hidden spot first, the bug spray even made my motor guide pedal white, now I dont let anyone spray anything within 50 ft of boat, just kidding but I am very cautions when sprayingLast edited by rydogggg on June 1st, 2014, 1:07 am, edited 1 time in total.
