Bottom of Impreza banged driveway apron

Your car is ten years younger (and has 1/10th the miles) but I suspect I know exactly where you hit. Most likely, the scrape you heard was the plastic under tray. This piece does what it says on the ...

Bottom of Impreza banged driveway apron

Can I insulate my van's floor UNDER the bottom, in the undercarriage?

I'm tall and can't quite stand up straight in my transit, or at least not with my feet together. It's not as bad as you think, even when cooking. Even to get this much height I had to be mean with ...

Is rust a deal breaker? Should I buy it?

Suggestions for refinishing suspension springs

Can I insulate my van's floor UNDER the bottom, in the undercarriage?

I don't think putting part of the insulation outside the bodyshell is going to be very effective. Metal is pretty good at conducting heat/cold, so your floor will tend to have the same temperature as ...

vibration/right side shaking when driving past 60 kph, but only when accelerating

I doubt this is CV joint/axle related as if that was the case you'd feel the vibration regardless of the throttle position. If the problem only occurs during acceleration I'd lean more towards the ...

Rust Underneath Car: How Much is Too Much?

Definitely do the screwdriver poke! I found a gorgeous 1999 Jeep Cherokee. Naive at the excitement of the price I failed to look at the underside. The inspection center poked and prodded. By the time ...

The metal strip does not look like it's part of the vehicle. My suggestion is to pull it out. When you do, use some kind of silicone caulking or even black Permatex sealant to plug the hole. You don't ...

Is it worth undercoating an already rusted frame?

It will make it worse. The rust likely contains some moisture to promote corrosion. You answered your own question. Long ago, Amoco did testing on undercoating. When new and continuous it protected, ...

Is this too much rust to repair?

If that is the worst rust on the vehicle, then I would say you have bought a solid car and there is nothing to worry about as far as rust is concerned at the moment. A wire brush down and a coat of ...

What should I do about metal strip sticking out from under car?

It appears to be attached to a plastic undertray, and looks like it's a parts label of some sort. If you're near the dealer, you can have them take it off (it'll be covered under the warranty), or you ...

Accidentally removed the rubbery coating from the jack attachment point

That definitely is a strange looking "metal." If in doubt, I've had pretty good luck with this rubberized undercoating. It boasts a "rust encapsulator" formula as well. Remember, prep is 90% of it ...
