What type of penetrating oil works best?

I like kroil or bp blaster i have had good luck witheither one .then go to the torch

Same here, Jerry. Both are tops in my book. :thumbzup: Gotta be careful with heat though.

Kroil is SO good, it works without even being used!

Well, it seems that way for me. About 4 years ago I bought a gallon of Kroil, and since then I've not encountered a single rusted nut that I couldn't unscrew without it. Kinda like carrying an umbrella, I guess - if I carry one, it doesn't rain. . .

i agree, it treats the metal before you even apply it

Kroil and PB Blaster are my favorite oils. And as many note, heat.

Will be trying some of the homemade solutions, like ATF plus acetone and wax plus heat. Lot of "opportunities" to test stuck stuff here!!
