Title: Underseal
Post by: Mo_1986 on February 03, 2019, 02:07:52 PM
Couldn't believe how bad the rust on the jazz was so got it all undersealed. Hopefully this will give it some lasting protection.

Unless you treated the rust first, or use a rust preventing underseal, the underseal WILL make rust worse.

The rust shows up mainly on the rear torsion beam, it is quite a nice thick section so will take a bit of corrosion. As commented if you put underseal over rust it can make things worse by trapping water.   Just make sure the rear brake pipes where they go across torsion beam to the wheels are not badly rusted.

Left it at the garage all day, was treated and mostly surface rust so nothing major. But looks really good now compared to before  ;D

Was it an expensive job, my 2006 jazz I just bought looks great outside and in but underneath is a different story. Rusty especially around the front wheel suspension and wot nots  :o
