Rear Spoiler Rusting Underneath

[Joe_Black]

I had the rear spoiler off the IronMan when putting the satellite radio antenna inside it and notice some corrosion on the mounting bolts. It wasn't into the roof sheet metal, so I just cleaned the bolts with a wire brush and lubed with some Mobil-1 synthetic grease to coat the threads real well before re-assembly.

If the fasteners corrode enough it will spread to adjacent material susceptible to corrosion. That's likely how it starts, as the quality control on bolts and such can sometimes be poor as they come from a vendor and aren't an Isuzu product.

Joe, just read your reference to the sat ant into the rear spoiler. Have been thinking of doing the same. I have the XM sys with the 1.5x1 inch bug, same you? Did you just drill thru the center post and then glue the bug to the top? Did you feed the connector thru or cut it off and splice it after routing it thru to keep the hole small? Thanks in advance

I have Sirius and took one of their mini antennas apart to put the element inside the spoiler, running the cable alongside the existing wiring for the 3rd brake light into the VX. Totally hidden and works great!

The new Dot antenna would likely fit without disassembly, and I know XM has some pretty small micro antennas that would also fit through the opening for the 3rd brake light.
