PSA: Soaking rusty bolts in ATF and acetone beat my PB Blaster on a stuck flathead V8
Pulled a 1950 flathead out of a shed near Abilene and every manifold bolt was frozen solid. Soaked half in the 50/50 ATF and acetone mix and half in store bought penetrant for two days, and the homemade stuff broke all four loose while the other side needed heat and still fought me. Anyone else mixing their own or am I late to this party?
