Hello Everyone
after my GT failed the MOT on a few things, i had recently fell into a problem that lead me to a point of giving up, as i had lost 1 solid week of work, from trying to remove the upper suspension bolt. It's the bolt that holds the horse shoe shaped part (forgot it's name) with two bushes both ends that the bolt goes through and holds the upper ball joint.
Now.. this thread is being created to help anyone who may end up having the same problem i had or any other bolt that is severely seized.
so I had a breaker bar and lots and lots of plus gas, which ended with the bolt head breaking off. This bolt was that seized, i had to cut the horse shoe off with a cutting disc, so only the bolt remained. i had tried hours of soaking in plus gas (penetrating fluid) i tried hammering it out, i soaked it in phosphoric acid and it just didn't work. So i come up with an idea I got 2 old radiator hose pipes with clips and pushed them over the ends of the bolts and over the outer tube. I come across a product called DEOX C Rust dissolver and this stuff i was on the fence with as most people normally are with so called "rust dissolvers" and i had a couple bolts/nuts that had been in my works ground for probably 30+ years and they was so rusted, it was hard to make a head and tail if it was a nut on the end of a bolt, so i left the bolts/nuts in this powder/water solution for 42 hours and to my shock... the things was to bare metal with no rust at all! heavily pitted but no rust and not even in the threads! picture below of the nut.
so i poured this powder/water mix into the water hose pipes i had put over the bolt/outer tube and left them for 4 days, which it seemed to of gotten in part way and dissolved some rust, but this upper bolt was defeating me and the powder mix just wasn't great enough (i still highly recommend the product DEOX C) and i had surrounding workers and others telling me to drop the subframe and just get the oxygen and acetylene on to it... well... i'm stubborn and i thought this bolt isn't getting off that easily... so i don't have any oxygen and acetylene no more and the price of it is just ridiculous.. then out of the blue a memory popped into my head of a tool i seen 8 years ago, which can heat metal up glowing red just like oxygen and acetylene, but it's flameless/much safer but at the time was a little over a £1000, so i told myself forget about it. Come the other day when i checked.. you could get one for £190 postage included and that tool is called a Mini Ductor and heats metal up using EMF Electric Magnetic Frequency and you know what... with just one day of using that while the subframe was still in place, the bolt slowly started to move, by heating the bolt up hammering it and turning it with pipe grips. There's no worry of it igniting anything as there is no flames and it doesn't run out of gas like oxygen and acetylene and this tool has to be the best tool i've ever purchased. The coils that do the heating, can be adjusted to how ever you want! i bent an old spanner with it earlier and even an old exhaust!
After the bolt was removed, i fitted the old hose pipes back over the outer tubes and filled them with a DEOX C water mix to completely remove the rust from inside it.
All i have to do is find a bolt and grease the inside of that tube up.
7 solid days of trying breaker bar/impact gun/hammer/acid vs 1 day using a mini ductor/hammer/pipe grips
so if you have seized bolts/screws anything like that and you want a tool that works out cheaper than oxygen and acetylene and does just a good of a job of turning metal glowing red, then get yourself on ebay and buy a mini ductor!

If you want a product to completely remove rust, buy yourself a tub of DEOX C Rust dissolver

Picture of the nut is of it being left in DEOX C for 42 hours and that was heavily rusted to the point it was hard to make out it was a nut and now it's stripped clean of any rust.
Now it's time for bed!
