Is it a meme?

Does penetrating oil even do anything? I'm almost convinced it's just voodoo at this point.

Prevents rust, or slows it at least.

put some on your ass and get back to us

It's too thin though, it would run off too fast for that, you could just use regular oil for that anyway.

It's thin, but it's penetrating.
Kinda like your dick, if you weren't a virgin.

sick burn bruh

I use wd40 all the time when I'm putting engines together. When I first get a bare block back from the machine shop I pressure wash the crap out of it to make sure no contamination is left. As soon as I finish with the pressure wash I come in with a big can of wd40 and spay it all over the engine making sure I hit any machined surface. Once the wd40 drys off I then coat the whole block in a light weight engine oil 0w20. With the block fully coated I put a plastic bag over to keep dirt out. Using this method I've let a bare block sit for a year plus before I started assimbling it with no signs of rust.

This here is the shit to use. If heat is still required it's not flammable so you can spray it on while heating and the heat will help it gets into threads and such

Who 3-in-One oil here?

>works so well they need three different products for one task
