I'm in the middle of doing the clean, and I'm torn as to where I draw the line. I have the LIM completely spottless (that was not fun btw), as well as the TB (previously optomized). I tried to soak the inside of the UIM by plugging the holes, but I didn't seem to plug them completely, so the B-12 leaked out onto the paint. The paint now looks dull, and has bubbled up in a few areas. Part of me says to just put it back on, and maybe do some touch up painting. The other part says to scuff it up and paint it completely. Has anyone had similar issues? If so, what did you do?
Another question, how nessesary is it to clean the heads? I'm just nervous about having that cleaner get down into the cylinders. Does it make that much of a difference?
Thanks
