Quote: I just put my e-body frame rail in my bath, i make forms to fit, been doing this for many years. I mix one gallon acid with 4 gal. vinegar and 4 gal. water. Cheaper this way but takes a little longer. Make sure you use a neutralizer to keep fron rusting back fast.
Do you mean your bathroom Bath-tub?
What ever container i make or use for my bath(mixture) Yes neutrlize in seperate tank to get in all the cracks, i use washing soda. USE outside!
