Pulled the seat and tank today to start cleaning everything up. I noticed on the back of the cab behind the tank it has a bunch of gas smelling thick tar/dirt build up. I started scraping it but was really making no progress. What's the best way to remove all the gunk? Some of it is soft like tar. I was thinking of soaking it down with a good degreaser or something to break it up. It's pretty much the whole back cab behind the tank. Ideas?
I might venture a guess that someone shot some undercoating back there as a sound deadener. Any gas leak that severe, over a 50+ year time frame , would have had a real bad result. And sadly, that technique is occasionally used to hide rust, bondo, or other undesirable forms of damage.
My first thought was that it was a fire retardant or something similar. The truck was a one owner farm truck. I scraped about a 1/4 of it off and the cab is in great shape behind it, no rust or holes.. It’s just a pain to get off. I wasn’t sure if this was something from the factory or from the original owner. I'll have to take a pic later tonight. It’s definitely a black tar like substance but hard.
My 56 has the same thing. It does not cover the whole panel. And harder than nails. Before anybody can say anything I know it's 57- 60 forum. But I have a 56 and two 57's and tend to lurk around here on this forum.
Hey Thrifty lurking is acceptable, I lurk on our former forum.
Greg have you tried a heat gun to loosen it, if it was me and was no real reason for taking it out I would leave it. According to my 1959 ford truck body, trim & sealant manual. several models did recieve a sound treatment 52 inches wide by 14 inches high.
Good luck in your quest!
I have three mid fifty f series trucks which all had this coating. I removed it by warming it up with a plumbers torch until it scraped off clean and easy. Only thing I would wonder about is if there is a "gas smell", it may ignite easy. Never had that in any of mine.
