Thanks Yonyon, that is what I feared. The line wrenches stay on the list I guess.
Merkava, I am going to add an angled ratchet to my list, as now I have the spot free by not bothering with the comfort grip.
Looks like it can come in handy with today's crowded engine bays.
At school, for a penetrating fluid, we use ZEP .45, and it seems to work really well. Me and a buddy had to bleed his brakes as they were a bit spongy, and we wanted to anyway (we are in the brake and road handling module and his fluid was black).
So, I had a bit of prior knowledge of how tough a bleeder could be to crack from a 2006 Cobalt I had. So the day before we sprayed them with ZEP, tapped them a bit with a brass punch, and around them on the calipers and the wheel cylinders.
The following day, they had a nice positive feel breaking loose, and these bleeders had never moved in 10 years or longer, and we are in the salty Rust Belt up here in Montreal.
Another time a few weeks ago, I had rusted lug nuts on a donated car, and the hub was jammed with rust. I squirted a ZEP bath all over them after unsuccessfully trying to break them loose with the gun.
After break and letting the lugs and hub soak, the gun got the nuts off without any problem at all. So this stuff definately works, it isn't a myth.
Another time I was pulling plugs out of an aluminum head on the same buddy's car, and I used shop air to clean around the plugs well and tried to break them loose. They felt a little uncomfortably tight, so in went the ZEP for our break.
After our break, the plugs seemed a little more agreeable.
I owned a can of PB Blaster once and didn't get a chance to try it out, forgot about it in the basement of a house we were selling. I got it from Canadian Tire, is that stuff any good? What about Liquid Wrench?
AeorKroil isn't something I'd find easily, though I have read on this site that Kroil anything is great stuff.
