Long story short...
A buddy of mine took the cyl heads off his engine mid summer last year. He called me a couple weeks ago and said he was getting ready to put it back together. He had it all wrapped up and sprayed down with something. I laughed and said to call me when it needed honed due to rust. This engine short block was in the truck OUTSIDE from October until last week. He had covered it with plastic, and cardboard. (we know how water resistant cardboard is)
So, he called yesterday and said it was perfect. NO WAY! He used Break Free CLP.
Anyone used this before and believe it? I use it on weapons, but never would have thought it would last that long or do that good for a block (especially bare cylinders and deck). OUTSIDE
Just passing it along. I will give it a try on blocks.... and a couple machine surfaces I always have to keep lubed.
