Solutions for rust on the bottom sill of Chery Tiggo 3: 1. Sand the rusted area; 2. Repair with rust-proof and waterproof coating. The Chery Tiggo 3 is a compact SUV under Chery Automobile, featuring a 5-door, 5-seat body structure. Its dimensions are: length 4420mm, width 1760mm, height 1670mm, with a wheelbase of 2510mm, a fuel tank capacity of 55 liters, and a trunk capacity of 550 liters. The Chery Tiggo 3 is equipped with a 1.5L naturally aspirated engine, paired with a 5-speed manual transmission, delivering a maximum horsepower of 116 hp, a maximum power of 85 kW, and a maximum power speed of 6150 rpm.
The underbody sill of my Chery Tiggo 3 has rusted, which is quite common since the sill is exposed to the elements, making it susceptible to corrosion from rainwater and salt. My approach to handling this is to first assess the extent of the rust: tap it lightly—if it sounds hollow, it means the rust is severe and needs replacement; if not too bad, I’ll fix it myself. Prepare the necessary tools: sandpaper, wire brush, rust-proof primer, and topcoat. Step one is to thoroughly clean the rust: rinse with water and brush off any loose parts. Step two is to smooth the surface by sanding it down until fresh metal is exposed. Step three is to apply rust-proof paint: evenly coat the primer and let it dry, then add a layer of topcoat for protection. Be sure to choose waterproof and weather-resistant products, such as automotive-specific rust inhibitors, available online or at auto parts stores. When parking, avoid waterlogged areas, and rinse the underbody after driving in the rain. Ignoring rust can weaken the vehicle’s structure and compromise safety, and delaying repairs might lead to costly part replacements later. So, act promptly—I’ve learned from experience that regular inspections and maintenance are cost-effective.
