Let-go was made by Krylon, but we can't have it anymore.Now i use deep creep by seafoam and PB.But nothing beat a set of torch. Pat
Ya Pat you got that right.. Around here they use so much Salt that your car underneath is trashed in a few years.
that stuff works...I turned over a can of it, by mistake, in my car...and the next morning....everything down-hill had dis***embled...!!!
Justice Brothers makes a rust penetrant/lube called JB 80 "twice as good". Anyone else use it? This stuff is also a rust inhibitor and is great because it is thicker than the others and isn't an acid. Zeke Justice gave me a can 20+ years ago and I have had a can or two handy ever since. I will test out the acetf tonight though. Great thread
Ok, this may sound nuts, but....My Dad use to restore old one cyl open flywheel gas engines. One of his buddies told him to go to the drug store or health food store now, and buy a bottle of Oil of wintergreen. Get a small syringe and use it on rusted bolts and nuts. Doesn't take much. I tried it and was amazed. Stinks like evergreen trees, but works great. And fast. If a bolt or nut is tight, not rusty, it won't help much, just like the rest of the penetrants. But if it's rusty it's great. It's pretty expensive for a little bottle, like I say, use it sparingly. Doesn't take much. It's poison, don't take it internally!! Try it, my buddies said, your nuts. I said...try it. I ain't nuts no more. Lippy
I recently mixed up a batch of approx. 75% Ultra Low Sulfur Diesel and 25% 15-40 motor oil because I ran out of everything else I had at home and didn't feel like going to the parts house. I put it in a little squirt can and to tell you the truth it works better than anything I have bought off the shelf lately.
Kerosene, brake clean and isopropyle, That seems easy enough. Theres no recipe, but maybe the ratios aren't very important from a home made point of view.
The 111 trichloroethane (TCA) in there is something that would be tough to find anymore because they banned the production of it about ten years ago. Last time I checked it was over $95 a gallon. It used to be a great degreaser solvent used in vapor degreasers, but they banned production of it because it was destroying the ozone layer. They have come out with a few other chemicals to replace that, but they're all expensive, and not something you're going to find in a hardware store.
Ah! That's likely the key as to why they no longer manufacture it... bummer. Why is everything that's good, not good for you? ~Jason
I did a similar test on my own 3 years ago with everthing listed except for LPS (forget the number). The Kroil outperformed everything including the brake fluid/acetone combination. I had the timer set for 1 hour of soak. #2 was Liquid Wrench. Amount needed was 2-3x that of Kroil. #3 was the LPS (I think it was #5). This stuff is hard to find. #4 was the Acetone/brake fluid mix. This was a mix that I had in a bottle for 2 years or so. Not sure that mattered but thought I would mention. I use Kroil for the fine work where an overnight soak is overkill. Kroil does seem to look dry when cured overnight. The acetone/brake fluid or ATF is good for working large areas that require an overnight soak. Never, ever use WD 40 on anything! I see people spraying this stuff on 1000,00+ fishing reels and even bait! Yuk, why not just use m80's tied to a rock!
I have used most of the top brands of penetrating oils for years working in NY and was a huge fan of PB Blaster until I found this stuff http://www.crcindustries.com/hd/content/prod_detail.aspx?PN=05002 Works completely different than most penetrating oils, read the write up on the web page, it freezes the rust instantly and it cracks. We actually have a Mazda Technical Bulletin at the dealer that specifies the use of Freeze Off for any repairs where rust might be an issue, usually exhaust work. This is the most impressive stuff I've seen in a long time.
Now this is what I was thinking. If ATF is good, wouldn't Marvel Mystery Oil and acetone be even better? Marvel Mystery oil on it's own does pretty good. Thinned down it'll probably seep everyplace. I have a gallon of Kroil that'll probably last me 5 years. Worked great freeing up old flatheads. I'll have to try a new mix on another stuck flathead. That CRC Freeze-off looks worth a try.
I use nitrocellulose embedded membranes in my job. One time I got chewed out by the people in the office because the company accidentally sent my order to them instead of the lab, they looked at the DOT stuff on the outside of the box and quickly wondered why I was ordering explosives in the lab I do like the humor there though, all you need is an ignition souce with the mixture and that stuck bolt will not be a problem.
So I just tried doing a 1:1 mix of ATF and acetone and they don't seem to mix together at all, the acetone is just floating on top of the ATF. Am I doing something wrong or did I use the wrong type of ATF? I'm using DexMerc ATF made by Coastal as it was the cheapest I saw at the store.
I use this stuff called "Free" by Cetrified at the shop. Works pretty damn good, much better than PB anyways...
You guys are making this too hard. Get a little bottle of oil of wintergreen and you don't need to be mad scientists and mix all this stuff. Plus your shop will smell nice too.
What lippy says. Oil of wintergreen. Best damned penetrating oil ever. Back in my early Navy days. Back in the days when they still used landing craft with Grey Marine engines, frozen clutches caused by salt air in hot tropical regions was a big problem. The throw out bearing would rust up solid on its steel sleeve. Also, the clutch dogs on the multiple disc clutches would freeze up. Quick trip up to sick bay for a squirt bottle full of oil of wintergeen. Squirt a little on the frozen parts. Wait a couple hours. Work the clutch lever back & forth a few times, and good as new. Not only does this stuff work great, but it makes your ride & shop smell great. Mice & spiders hate the stuff, and will flee the area. No more chewed up wires or upholstery. Since retiring from the Navy, I've always kept a bottle of oil of wintergreen around for those stubborn jobs. WD-40 & the others work great for squeaky door hinges and things of that sort.
For those of you still having trouble finding Acetone, it can readily be found at Ace, Menards and Home Depot.
