I'm about to replace all my Tuscans suspension bushes and thought this product might be helpful if some of the bolts are seized. Has anyone used it, or any other recommendations?

Plus gas is the best thing I've ever found by miles - frees off seemingly impossible to undo bolts.

Cheap too. biggrin

I bought this stuff to take off the exhaust manifolds on my TVR S. Local specialist said "If you get all 12 bolts out without snapping one, put your pension on the lottery, because you're a very lucky boy".

I used this stuff, soaked the bolts a few days before. Well you don't know if the stuff worked or if the bolts would have come out anyway, but they did - all of them.

I've used it since on other rusted bolts on suspension etc and it has always worked. I was so impressed I bought another bottle last week!

I also use plus gas generally, but I keep this stuff for the really awkward stuff - because of the bottle design and the long neck you can drip it exactly where you want it.

I was waiting somewhere (Drs?) recently and picked up a copy of a vintage motorbike club mag which had an interesting article about loosening rusted bolts; I noted down the info which was apparently based on some sort of standard rusting of nuts/bolts as a starter with the release agent being then allowed to soak in before loosening - results were:

Release agent Torque (lbs)
None 516
WD40 238
PB Blaster 214
Liquid Wrench 127
Kono Kroil 106
ATF/Acetone 53 (this was apparently a home brewed 50/50 mix)

I've not heard of some of the above stuff but whilst the testing may not have been totally lab/reproduceable, etc. the results sound interesting to say the least so it may be useful to someone - interesting to see if the home mix is as good as is suggested so if anyone tries it let us know.

If you run out of "proper stuff" a few drops of diesel can work wonders !

Whatever you use the longer you can give it to soak in the better, if planning on taking manifolds off on Saturday, for example, start treating bolts two or three days before (IMHO)
