Best cocktail

Have not heard anyone mention PB-Blaster yet? That is the best Penetrating Oil on the market. Does not evaporate right away.

Whatever Penetrating oil you use, give it "Time" to work, days . .

If I ever have to pull off rusty bumper bolts, I start soaking them down with PB-Blaster a week in advance and keep re-appling it to keep it wet.

They come apart nice then when I have a go of it.
