Hood "intake" on Giulia Spider

**NMS** · #1 (**permalink**) 05-29-2009, 01:30 PM

On my 1964 Giulia Spider, the air intake on the engine hood, is now just an opening (with the chrome decoration), not blocked. I got a hood mat to glue on the inside of the hood, and realized that water will get between the hood and the mat (not good...).
How is this prevented? Is the block out panel (saw it in the parts book, but not in person) sealed? If not, how is water drained? Anyone know a source for the panel? Is it reasonably easy to make one? Could anyone post some pictures of the arrangment?
Also, is regular contact cement OK for gluing the mat to the hood?
Thanks!

Hallo,

Just a vinyl sheet glued on the intake holes ('64 spider)
I also find this strange.
The insulation covered everything.
I use classic Pattex (yellow one), the transparant one is not heatresistant.
Make a test before, with your insulation.

groetjes,

In the interests of anyone reading this thread in the future ... to be as original the opening is blocked by the strip of steel that concept 101 displays ... but the steel is covered with a thin black vinyl which had an equally thin foam layer bonded to it.
When installed this caused the vinyl to be pressed against the inside surface of the hood/bonnet creating a water seal. No putty or sealant was used. The vinyl was semi-gloss or chassis black in color with a smooth surface - no texture.
With the chrome trim installed, the shadowing completed the illusion of depth; it was effective since the vinyl was compressed by the hood and protruded slightly through the openings.

Many Giulia's saw this treatment removed by early owners wishing to make their Alfa "a little different".

Wow! Thanks for all your accurate descriptions and pictures!
I think it won't be too difficult to get it right...

GTD is dead on correct. Mine is original an has served as a pattern for many cars, but his written description says it all.

Hi Jim,
The metal strip is painted chassis black under the vinyl and foam. Here is what I discovered. the vinyl is well replaced by 3M Electrical Vinyl tape. The foam is very thin and serves to push the non shiny vinyl into the holes in the hood for both a water tight fit and the illusion of them being real holes.

Does anyone have a photo of the plate with the vinyl still on it? Mine came without such. Does the vinyl cover the entire plate?

The vinyl and foam cover the entire plate. The vinyl goes around the ends of the plate and these flaps are captured under the end nuts that hold the chrome and backing plate in place.
