Saw this over on the HAMB and it is the cats meow... at least I was purring after using it. Also after reading the Kroil vrs PB Blaster thread here I ordered some kroil and I find it hands down better than the PB I had tried up till now...
I was able to remove all the original bed/fender bolts without a single loss which was about 90% better than my past experience with similar bolts or screws on this truck. I gave the bolts several blasts of kroil over a week or two before tryng to remove them but the key for me was taking a small wire wheel to the exposed threads, then working the screw both ways. Tighten a touch more then loosen then tighten and hit with Kroil then loosen. The little tool worked great to bust things loose while turning.
