This may be on here already or not but I thought I'd pass it along anyway since I just had to use it again.
Had a bolt on my K1200RS stuck and had tried everything. Every spray penetrant I could buy, pb blaster,etc. Beating with a hammer. Heat. Cussing. Etc. Was about to weld on a piece of rebar to help the beating process when fortuitously my old man called me, told him the story and he gave me this recipe.
The best penetrant ever known to man
Mix 50/50 Acetone and transmission fluid
They don't really mix well so shake before each use
I used a tattoo wash bottle, the little bottles with a straw on top you squeeze. I try to keep them on hand in the garage. Use them all the time.
Anyway. Mixed it up. Squirted on a couple times. Was going to wait over night but was actually about 15 minutes.
Turned bolt Off easy as pie.
Have used many many times since then with 100% results
just had to use it so I wondered if anybody else has some cool recipes?
