Rust Inhibator would be good as well. It's specificly used for exposed clean metal.
Another question is, do you guys shave the entire lip off the fender? The bodyshop that I had mine done only shaved until the weld spots. They said if they shaved past it, the rear fender could buckle on any large pothole impacts or even railway tracks.

That's awesome! Can I ask what method you used to roll? Did you have to do anything special to get the results? I was hesitant to attempt it since it looked pretty hard to roll but if you got a good roll I'm willing to do it too.
I need to fit 18x10 +5 in the rears, currently at 18x10 +20

So get a belt sander and shave it all off ! !

Here’s the inner lip areas after everything was shaved smooth and then primered. This was followed by silver and then all but the last ½ inch by the lip was sprayed with rubberized undercoating.

Here’s what my set up looks like with about 1 to 2mm of clearance between the fender and tire, but I have Zero rub at any drop. If you roll the lip you WILL NOT get as much clearance as this set up since the thickness of the metal gives less clearance than shaving it off. I'm running 295 tires on 20x 11 rims, so this is pretty close to the limit without pulling or cambering. Since this discussion is ONLY about shaving options I won't go into those other options.

If you Do A Search there are several threads talking about dimpleing when you roll. No One who rolls is going to guarantee you that they'll pay for a new paint job if the fender dimples or give you a 3 year warrantee that the paint won't crack. There's always some level of risk with rolling.

I've never read about it being used for this, but my wife uses a strong rust preventative paint on her track car on the interior, roll cage, etc. Interior of her car is mostly exposed metal that has had welding or sanding, etc. Bet it would be good for this purpose.

This stuff is crazy, so be careful when you use it. Definitely take off any wheels, etc because whatever you get it on, it isn't coming off.

That is ENTIRELY incorrect. Maybe on a Honda/Acura with thin sheetmetal that's true, but not the GS. There are many members on this forum for that have been running full shaved with no issues for 5 + years. Just between me and one other local member, we have over 100k miles driven.

BTW Your work looks amazing, what brand of rubber undercoating did you use?

I can't remember what brand I used. I did this mod a long time ago.
Just remember DO NOT get the undercoating that does not dry to the touch. That stuff is a sticky smelly mess. It's basically spray on tar.
Test it on another surface before trying on your car.
