As a PTW owner I have dealt with this first hand. You can play in the rain easy enough, but if you suspect your gun has been moisture compromised unplug the battery immediately as stated. You can get the sealed front optics and newer versions of the computer inside the cage are better at not getting wet. That being said, if you drop it in a deep puddle, are in torrential downpour or just have one weird misfire, unplug that battery. Go home, strip down your gun and use duster cleaner to clean it immediately. DO NOT USE HEAT!. This will kill your boards faster than water. Pull it all apart, dry out the boards and motor with a duster can and let the rest sit and dry. I've played through severe rain storms multiple times without incident with my PTW without issue, but the first huge rainfall I tried to dry out my gun using heat and didn't disconnect the battery right away. Everything ended up fried.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
