ok so i went boggin this weekend and got the ford COVERED:D. kinda forgot about the horns mounted where the spare tire was…so a few hours later i thought about it and honked them. They sounded retarted at first but then they got louder. guess they just had to blow all the mud out of them but they still aren’t the same as they were… i took a brush and tried to get most of it out but still not quite right. it is ok to just spray a hose up in um? dont wanna F um up but they might already be…or is there a better thing to do? 
what horns do you have, regardless spraying water in them wont hurt them. If you have nathans than water in them wont hurt since they are on top of train and get rain/snow in them
