i undercoat frequently in my detail shop and i am curious to find out who else does it. i want to kno im u guys spray the brake lines n the various hoses that run along the frame. some of my management wants them sprayd n some managers do not, i was just wonderin how u guys do it

I spray 'em if they're new. I don't if they're old. It makes it a pain in the ass to change if they're covered in it.

I have been undercoating for years. Started out with a paint brush and a sleeper lol but when I started to work at a dealership I got into spraying. I spray new and used , if the undercarriage is dirty I wear a rain coat and wash it the same as the outside dry it with a airgun then apply the soundgaurd.
