Can Horns Go Through The Car Wash?

one of my buddies said i cant wash my truck because i have a train horn and it would rewing it now i looked on the internet and couldn’t really find any thing thought you guys would know about this first hand

i pressure washed my k3 inside of it and everything and its fine, and ive went threw some like foot deep puddles and filled the horn with water blew it all out and its fine man, So dont worry unless u got like some really poopy horns lol

look what happens when horns are on the top of a train… if you get a real train horn, i wouldnt worry about it

i’ve taken mine through many many carwash’s with the 8 horns compressor and tank under the truck

Well what kind of train horns do u have?
