In the article it says there are two ways to do it. I think the second way is kind of cut off, is it suppose to be like that or is info missing? Also, don't they have sprays that can do this? one more question, will the dealer do it?
I've never met a dealer that would do it. Detailing your engine is a pretty easy thing to do, but there is a certian amount of liability in it. I don't think they want to be responsible for accidently shorting out your electrical system or something.
