How to fill this ..

[Zen]

Have this divot, hole, crater in the hood scoop of this Johan Torino and what would be best way to fill it. Started out as a large bump which I sanded down then broke thru to the crater.

i'd glue some thin sheet to the bottom then fill it

Two-part filler of some sort, either glazing putty or epoxy.  One-part spot putty from a tube will shrink over time, you don't want that in a prominent place.

I didn't notice it was a hole, the same still applies but you must have something below to close that off.  Use CA glue for the patch, solvent cement will take time to fully cure and, like the one-part spot putty, will shrink.

Hood is molded in on this one, promo style. Thin layer of plastic left on the inside. Could break thru it and glue some thin sheet and putty the top side?

Never seen that before.  If you've got plastic on the lower side, don't bust it out. 

I'd fill with two-part epoxy filler on top.  The first layer would fill most of the divot (pack it into the corners, don't leave gaps), then grind or sand the edges of it to feather in the final fill.

If you are building this as a curbside and not worried about the underside of the hood, I would find some round sprue or styrene rod that is close to the same diameter as the hole and glue a small section of it into the hole.  For cement, I would use tube glue.  Put a good amount of glue around the rod and then insert it into the hole.  The excess glue will ooze out and form a good seal around the rod.  Once the glue has had ample time to dry, cut off the excess rod and sand the area smooth using various grades of sanding pads or sticks.  I have used this technique several times in the past and have never had a problem with shrinkage around the repair, as you might have with some putties.

I agree 100%
The less filler the better. 
Glue a short section of rod into the hole with a good plastic cement, let it dry thoroughly, and then trim the rod close to the surface and sand level with the surface.

After that, a thin layer of glazing putty and some light sanding will do the trick.

I use plastic as much as possible for filling holes.

The less filler you use, the less you have to worry about shrinkage, cracking, etc.

Not only that, but if you glue it in place with a plastic solvent, should you have to strip a paint job for any reason, the plastic won’t be affected, so you won’t have to start the body work all over again.
