2020 Rubicon (600 miles)
Has anybody experienced rust on the welding areas of the frame?
Thank you, I have a service appointment next week. I'll let yall know how it goes. I was also looking at por15 to use on the frame and fluid film for the internals of the frame.They did not prep the frame right leaving flux on the welds. Pre expat surface treatment should have taken care of it. I would call the dealer and complain, they may paint it (they did on my TJ). If you are not too worried about look and dirt pickup, the best material you can coat the frame with is a wax. Will resist corrosion 10 to 20 times longer than paint and is self healing, meaning if you scratch it, it will reflow and cover the scratch. I can take a picture of where I drilled holes in my TJ fender and waxed it. 16 years later (9 in Michigan, 1 in chicago) and no rust. Bad part is it is sticky. And pucks up dirt. I use X121b from Daubert Chemical Company and it is available in spray cans or liquid. Best stuff I have found. BTW I am a paint chemist and have been inventing paint for 30+ years.
