i had a random thought today since i spend alot of time with nothing but my random thoughts in the truck.
is the brake cleaner you are using flammable? alot of the new stuff isnt.
i like to use soapy water to find leaks. an unlit propane torch works too in a pinch.
edit: i try not to come off as arrogant or crabby, this 14hour work day shit is killing me. if i am not clear just ask and i will try to explain better. stuff that makes sense to me usually doesnt make sense to anyone else.
