So it sounds like I can find better things to worry about than corrosion with the clips or fittings.
Or, put another way, when THAT is the biggest problem I have with this truck, I will be in a very good spot!
Thanks for the input. FWIW, the lines have been very easy to work with so far, and look good. My OCD kicks in about the straight pieces not being totally "straight" like fresh lengths of steel, but I think I can deal with it!
