A better penetrant?
I have been working on a Roadster project that is in need of an engine. I have a AA truck with a Diamond engine I bought from Northern Minnesota where it sat parked out in the weather since 1966. The rusted engine looked typical for this area (rusty), I pulled the plugs (with difficulty) and sprayed Lubri-Magic in each hole, in number 2 the valves were covered with surface rust, I let it sit for about 10 days, put the crank in and it turned without resistance! When I got the truck home I tried it several times and bent an old crank without turning it at all. I heard about the penetrant from an OLD guy I saw at Lowe's, he repaires electric motors and says it is the best stuff he has ever used -- I had my doubts because it is Bio-based. After the first success I sprayed it on every rusty nut and bolt I could find -- the head and manifold studs will be a good test, I'll try them and get back to the forum in a week or so. Later, E LaBrash

A better penetrant?
Hi Elmer, I did a search on the product you posted and came up with no information. Where is it available?
Hope to see you at Whitewater this Fall...around the week of October 9th...correct? Dave in MN |

Re: A better penetrant?
Best I've used is a 50/50 mix of ATF and acetone (yes, automatic transmission fluid).
One of the magazines ran a test, and, IIRC, Kroil came in second to ATF/Acetone. Steve |

I use the ATF and acetone too but a leaner mixture. Like 1 part ATF and 5 parts acetone. You see, the idea is to make the mixture so thin it will run in a very small opening. The ATF stays after the acetone evaporates off.

Re: A better penetrant?
I'm sure it is available all over, I got it at Lowes -- (most stores are the same) in toolworld on the endcap between aisle 64 & 65. Yes, Whitewater is this year, see you there! I hope to have an "A" to drive, EL

Re: A better penetrant?
Thanks for the tip. I have typically used PB Blaster on rusty bolts with good success but I'll give Lubri-Magic a try!

Re: A better penetrant?
That is the best thing I've learned off the net. It workes great. A little heat before application doesn't hurt either.
