I picked up a very clean, relatively low mile Volvo XC70 (2004) for my recent relapse of my life-long skiing addiction.
Going under it, it was very clean with all bushings, etc. in good shape, no issues to be found. It's a PNW car so not surprising. I did find the exhaust hanger on the muffler rusting badly. I was thinking to scrape/brush it as best I could, then use some Permatex Rust converter on it. After that, exhaust or grill paint? Ideas? The exhaust is all otherwise excellent so I need to arrest this asap to avoid a bigger hassle later.
The lug bolts were also rusty. I vinegar soaked them and then took away most of it with emery cloth. Then I gave two coats each of rust converter, Zinc coating (cold galvanizing spray), then a top coat of aluminum paint. They look good now but I know this won't work on exhaust as the zinc and paint layers won't take that heat.
