I’m currently doing a purpose built restoration (daily street/off-road use/not show quality) on my ‘83 K5. I’d like to hear ideas on how to coat the underside of the hood. I have sanded it down, sprayed Eastwood internal frame coating (only green was available) inside the cavities. Should I also spray a rubberized coating inside the cavities or should I just prime and paint everything at this point? Or, has anyone sprayed the entire underside with rubberized truck bed coating? Other considerations, sound deadening coatings, stiffening coatings to stiffen the hood outer skin, heat tolerant thermal ceramic coatings, ease of coating removal during the next restoration, rust inhibitor coating…? Thanks!

Just my opinion but the rubberized coating is extremely hard to get back off. I used these 2k products from eastwood. They are ceramic based 2 part so its tough as nails.

Back in the 90's, my best friend had a bedliner business, and I had him spray the underside of the hood of my 65 Suburban(gloss black). Yes it added weight, but it looked killer and sounded very solid. I also had him do the gas tank on my original 65 Chevy II Nova 4 door. Rocks were always hitting the tank, so this protected it very well.

Removing any coating from a surface like that is virtually impossible so consider that.
Otherwise, prep it well and paint it.

I am cautious about the hood, as you see so many that have been bent, so lube the pivot points, I agree with Todd, (Grit Dog), paint, doesn't add weight. I wash my motors a few times a year, so I do not like hood insulation because it does not stand up to the pressure washer, but hood sound deading material, (dynamat) does help keep things quieter.

Removal of old undercoating is not bad using dry ice.
You could cover it w/ diamond plate.
