Can you point us to more information on this? We're struggling to find a reasonable mechanism for blocking light from the baro sensor on our MicroPeak product. I've done some testing, and light shining on the sensor is really bad. We tried some self-stick porous foam (Poron 50-30031-12X12P), but the adhesive isn't porous enough and when stuck firmly to the sensor, it makes an air-tight seal. Glad you're finding ways to avoid the worst effects of corrosion. Not sure what that spray will do on top of a GPS patch though; those are rather sensitive to any materials. And, you probably want to find a way to keep the gasses out of the inside of the baro sensor too, if you can. -- -keith
