Since removing my dirty underhood sound deadener (probably a bad idea), I've noticed there are many holes in our hoods around the 2 non functional hood vent areas. As a result, I have water related misfiring whenever it rains because I noticed that water drips directly onto the spark plug coil pack. It doesn't happen when I was my car, but that's probably because the rain is more constant. I've been using different types of RVT silicone, but it doesn't hold forever.

So, I'm looking for a more permenant solution. I've heard of different Bondo products, like 'Metal To Metal', that might work. But I can't seem to find any information on them. Do you guys know of any filler that I can use to plug up the holes on the underside of my hood and be able to handle all the heat from the engine?

 

Get a fiberglass repair kit. Bondo is only used to fill small depressions not holes.

 

Ok, thanks...Will it withstand the heat though?

 

You might want to try a pool patch putty The stuff gets as hard as a rock and can be painted, cheap too. I use it to fill holes in metal doors all the time.

 

Yes, all these products will handle the heat just fine. Really not that hot.
Not sure why you think removing the insulation would be a problem either? The "SS" comes without any.
