We have a full resto shop mopar only in Alberta we always take the inner out of the hoods so we can get at the outer skin for repair and to get all the rust out from under the bracing. We have tried different things for a sealer etc to put them back together I agrree that you want to use the flutter foam if you do not and glue it in place every place that you glue it will have a dimple from shrinkage from whatever glue or sealer you try. As stated it does not have to be glued together the foam works just fine and will not dimple in those spots. We ahve had them where we glued them let them sit for a month and still down the road they will shrink Hope this helps
