comment How to glue foam panel to painted metal (underside of car hood)
@OlafM, can you describe the frequencies that you are trying to attenuate? If you're trying to reduce higher pitched buzzes and hisses, the materials that you describe will help. For low frequency, high amplitude sounds (like a lot of engine noise), you need more material due to the longer wavelengths. That requires more space which is why a lot of this dampening happens inside the cockpit and doors.

Are you really trying to reduce the sound reaching you in the cabin? If so, maybe we should address that problem instead. It's related but the options are much safer.

comment accidentally placed oil in the atf reservoir in a BMW 520d. How do I fix it?
The example that you describe is not at all the same. This is not an answer to the question.

Tony, see the previous question. Yes, running mismatched tires can damage your car.

comment Does using an impact wrench instead of a breaker bar prevent damaging to nuts or bolts?
@AllanXu, it's true that an impact wrench is different. You can also break bolts with them. Proof by existence: I've done it many times. They aren't magic.

comment After putting on new winter tires, my steering is weak/light
@Andrew, it depends - we had some nights that were below freezing in the last few days. Of course, the next couple of days were super warm. But, did I spin out on cold roads while driving home from class? No and nor did I worry about it.

comment Hit a wall with my car how to remove paint?
@Nav, if the mark left by the gate is coming off with water and a cloth, that's great. However, make sure that you rinse (and probably wash with car soap) the area really well before you start. There's likely some extra dirt and grit in the area and you don't want to rub that into your paint while you're rubbing the gate paint off. With respect to corrosion, you can't really know until you clean up the mark. At that point, you can fix any remaining problems.

comment Why should I clean bug and bird debris off my car?
I don't think that linked answer is a good one: using sandpaper to remove a bug sounds like crazy talk

comment How to dispose of engine coolant?
If you go to the EPA site, you'll see that they recommend recycling it due to its connection to natural gas. They link to www.earth911.com for those seeking recycling information.

comment How to dispose of engine coolant?
This is incorrect. I am looking at the EPA site on recycling used antifreeze and it is clearly hazardous and they definitely do not recommend putting it in any water supply.

Kim, I suspect it's not a terminal problem (just super annoying). See my answer below.

comment Removing catalytic converters on a 2000 v6 Mustang?
Okay, my answer is below. To be clear: I support the quest for cheap fun. I just don't think this is a good idea.

Why are thinking of gutting the cats? Are you thinking it will add power? Or are you just looking for a louder car?

comment What are the implications of driving through flood water when I have a high air intake?
@Jerreck, because the spark plug holes are vertical. My engine is flat so it's harder for it to retain water in the spark plugs. A V engine is somewhere in between. Assume that the probability distribution is something like the cosine of the angle from vertical.
