I had no idea these trucks had aluminum panels, learn something new everyday!
My Olight flashlight has a magnet on the tail and wouldnt stick, so it definitely is aluminum. Scraped the bigger patches and they flaked off to reveal white powder patches underneath. The ones on the folds were pretty hard scrape, looks to be sealant. No accidents all factory paint, only has 36k miles. So its aluminum, do I need to sand and prime those areas like steel? I'm not sure how aluminum corrodes compared to steel but I dont want to have a hole there! |

Aluminum contaminates VERY easily, shops need to use special equipment to do it right. |

Quoted: 2005 Ford Expedition, rear hatch. Looks like typical rust bubbling but hasnt broken through anywhere and pressing on it with a fingernail it seems pretty hard so I'm not sure. In the rust bubbling I usually see, when it gets that big, a bit of pressure and it crumbles up? http://i239.photobucket.com/albums/ff116/g300d/Mobile%20Uploads/20160728_102415_zpsqp3u1xsn.jpg http://i239.photobucket.com/albums/ff116/g300d/Mobile%20Uploads/20160728_102419_zpscexfb81b.jpg Seam sealer or panel adhesive. |
