Even on a clean car, your paint can feel rough. That’s bonded contamination—rail dust, tar, sap—stuck to the clear coat. Decontamination is a two-step idea. First, use a chemical iron remover and a tar remover to dissolve what you can without touching the paint. Then, if needed, go mechanical: a clay bar or synthetic clay pad with plenty of lubricant. Glide in straight lines with light pressure, and you’ll feel the surface turn glassy smooth. This step dramatically improves the look and extends the life of any protection you apply later.
Protection is where beauty turns durable. You’ve got three broad lanes. Traditional wax gives a warm glow and is easy to use, but usually lasts weeks to a couple of months. Paint sealants lean synthetic; they’re slicker, more chemical-resistant, and can stretch to several months. Ceramic coatings are the long-haul option: serious chemical resistance, strong water beading, and a “candy shell” feel that can last a year or more, sometimes several, with proper care. The trade-off? Coatings ask for meticulous prep and more careful application and curing.
Think of your car fender as the armor that wraps around each wheel opening. It is the curved body panel that frames the tire, catching road spray, deflecting small stones, and shielding the door edges and engine bay from debris. When a shopping cart kisses your car or you misjudge a narrow garage, the fender often takes the hit first. That is by design. It is a sacrificial, replaceable skin that protects pricier parts around it.
People mix these up all the time. The bumper is the bar at the very front or rear designed to absorb impact loads. The fender is the side body panel that frames the wheel. If you scuffed the corner turning into a tight parking spot and the damage is above the wheel arch, that is fender territory. A cracked plastic cover at the nose or tail is usually the bumper cover, which sits over a reinforcement beam.
On push-button start Trailblazers, look for the small release on the fob to slide out the hidden mechanical key. With the metal key removed, you’ll see a slot or seam along the fob’s edge. Insert the tip of the key or a small flathead screwdriver into that notch and gently twist to split the case. For older, non-flip remotes, there’s often a little groove where a coin can be twisted to open the shell. Work slowly and keep the halves aligned so the rubber buttons and the circuit board don’t jump out.
Good news: replacing the battery does not typically require reprogramming. The fob and vehicle remain paired through stored codes, not battery power. After the swap, walk a few steps from the Trailblazer and test lock/unlock and the hatch. If range is back and the buttons feel snappy, you’re set. If it’s still intermittent, double-check that the battery is fully seated and oriented correctly, and that the case fully snapped shut—poor contact or a half-latched shell can make the fob flaky.
Love it or not, Tesla still sets a high bar for efficiency, charging access, and software in 2026. The refreshed Model 3 and Model Y remain the default picks for people who want strong range for the money and a charging experience that just works. The Highland updates made the Model 3 quieter and cleaner inside, while the Model Y continues to be the Swiss Army knife of family EVs. Cybertruck, after an early hype cycle, has matured into a distinctive option for people who prioritize utility with a dose of sci-fi design. What keeps Tesla near the top is the ecosystem: widespread Supercharger access, increasingly open to other brands, plus consistent over-the-air feature updates. Driver assistance is still driver assistance, not full autonomy, and you should treat it that way. But if you want efficient road-tripping, seamless charging, and an active software roadmap, the Tesla lineup remains a safe, high-impact bet in 2026.
