I'm replacing the gas tank and rearend in my 68 and I'm curious on what people have done to clean the underbody to make it look new. Im scrapping it now to get what I can off then I'm wondering what other tool I could use to get as clean as possible. Any chemicals I can spray to help with this, special tool I could buy. Wire brush doesnt really cut it, also have small die grinder but I cant get it in all the smaller tight spots. Plan to get it the best I can spray some rust protective paint and was going to spray with a truck bed liner and or a rubberized underbody spray. I did the truck liner on my other import car on the inner wheel wells and turned out great. Any help appreciated!
