Undoing rusted bolts?

[rowinz]

Anyone know a secret squirrel way to undo rear towbar bolts that have rusted in (to captive nuts)? Aside from dousing with CRC, undo a bit, CRC, do up, undo a bit more....takes a while with 12 bolts. Anything better for it than CRC?

From what I can tell the bolts themselves are fine, its just probably some rust on the threads...

i have found that a product called breakaway made by cyclo works way better than crc but they all will work eventually, if you dont have to use the captive nuts again you can be rougher and use a bigger bar biggest problem is if the nuts turn you are screwed and will have to cut them anyway, good luck,

wire brush the thread crc and your away.....always works for me

not sure if it works with captive nuts but using a bit of heat in sometimes works but not to much.
i have used it for spokes tha rust tight on my bikes ut that is a slightly different purpose

Heat or smack the top of the bolt with a big hammer to shock and break the rust bond.
Whilst the post above says not to much heat, if you don't want to reuse the bolts I have always found that no rusted bolt is a match when it starts glowing orange. Then it will always undo.

crc do a product called penetr8, ive used it a few times for siezed bolts and nuts , it works quite well

ive also seen guys mix up a brew of MEK , nail polish remover petrol and paint thinners - that also worked

Cut into the nut so far with a cutting disk or saw then whack the MF with a coal chizel.Works every time.

You wouldn't want to light a smoke when using that brew
By the sounds of it this would also make an awesome:
-engine degreaser
-gasket stripper
-paint stripper
-sustitute for "P"
-nasal decongestant
-laxative
That is some that spring to mind quickly, I am sure other people could think of a few more uses.
