fire4t3 Posted July 9, 2013 Share Posted July 9, 2013 A few b models I have looked at all have rust on the front pillars down below the windshield. And right above where the air cleaner is plumbed in. Is it repairable? Quote Link to comment https://www.bigmacktrucks.com/topic/31879-b-model-cab-rust/ Share on other sites More sharing options...
j hancock Posted July 9, 2013 Share Posted July 9, 2013 With patience, it can be repaired.B cabs were made out of real steel so they can be fixed.Jim Quote JimIt doesn't cost anything to pay attention.

richard-b61 Posted July 9, 2013 Share Posted July 9, 2013 If you don't have a mig welder, get one. I bought a lower priced one from tractor supply and have been grinding the bad metal away on my B61 and welding in new metal patches. Its working good, and saves on body fill. Just have to set the welder on low so you don't burn through the metal. Tractor supply also has small sheets of metal that work perfect for this.

Maddog13407 Posted July 10, 2013 Share Posted July 10, 2013 yup mine has been fixed once or twice already. the a bad spot. believe its where all three panels come together and they are overlapped so they rust in between. you need to cut the outside away, sandblast or seal the rust then replace the outside.

fire4t3 Posted July 14, 2013 Author Share Posted July 14, 2013 After you cut and patch the area, can you reach up on the inside to clean and prime or put rust inhibitor on the backside so it doesn't rust anymore?

220cummins Posted July 14, 2013 Share Posted July 14, 2013 Not really. There are a few pieces of metal that join there. I usually just back prime and seal up the area when I have the rust cut out.
