My wife named my car Buzzy after her first ride.

I bought some sound deading foam off Amazon, both for inside the doors to improve the speakers and for the top of the engine hatch. Original sound deading mat in the engine hood was getting frayed. Ripped it out and covered the whole inside including rain cover. Added windows that I taped over but didn't stick to the steel over the info cards.

I don't have actual measurements and it could be somewhat of a placebo effect, but Buzzy is not nearly as buzzy as before. OK wind noise is still 80% of the noise.

$30 and maybe a half hour well spent.

Good idea

There is a reason why the engine cover is vented

The sound deadening only appears to cover the vent cover, no? The vent itself is still open at the rear of the lid (top of the photo).

Yeah looks like the vent opening is still there.

I just added some sound deadening material below the storage compartments. Around the plastic evap cover and fuel pump. Noticable difference!

I didn't cover up the sides of the rain cover so I didn't affect ventilation.

It is hard to see.

Is this supposed to be fire retardant? Is the other side a black sticky substance? (Like the stuff Eastwood carries)

This is the stuff I used. Amazon.com: Siless Liner 157 mil 36 sqft Aluminum Foil Finish Car Sound Deadening & Heat Insulation Closed Cell Foam - PE Foam Sound Deadener : Automotive

Doesn't say anything about fire retardant, does say it is good up to 215 degF

The dynomat I used is right above the fuel tank. It there is fire in that area I have bigger problems.

I kilmat my spyder but focus more on floor pan, doors, and firewall (from inside the cabin). I believe it help a lot but I have the added help of a hardtop. I don't know how that insulation would help cabin noise on the engine lid unless it was rattling before for some weird reason.

Looks pretty close to the same stuff I purchased from Eastwood. The price is a little higher but I got mine in one of those deal of the day deals.
Seems to be much the same material as snow and ice shield use in the construction trades around windows and doors.
