Open celled foam must be sealed prior to painting. The seal is a simple mixture of white glue thinned with water and brushed on.
Yes, otherwise you will seal in moisture causing potential rot and mildew.
Any primer is going to seal the surface which is all the gesso is doing.
Any good alcohol or lacquer based sealer will work. I use shellac if I'm staining and Kilz if I'm painting.
I believe that you prime than paint than seal. It depends on the paint you are using and what you are painting A lot of the exterior paints used today don't require any undercoat. However if you are painting over a previously painted surface you must keep preparation in mind.
rubber seal around the opening on the hood is loose and preventing the sunroof from moving down and sliding open.
Spray foam insulation forms a powerful, airtight barrier through a simple chemical process. First, two components are mixed and sprayed, causing rapid expansion that fills all gaps. This creates a solid seal, eliminating energy-draining air leaks. Its high R-value, especially in closed-cell foam, effectively blocks heat transfer, leading to stable indoor temperatures and lower bills. Additionally, closed-cell foam resists moisture, preventing mold and structural damage. Open-cell foam, due to its texture, dampens sound. Ultimately, spray foam enhances energy efficiency, comfort, and saves money.
Seal it to the back side of the tub? There should be a foam ring that is beveled that goes between the tub and the drain. When you tighten the cover plate down, it compresses the foam and seal the drain. Seal the hole so that it doesn't work? There is probably a cover plate that is solid and would seal on the inside surface of the tub.
check to see you have a thermostat installed. If you have one then you have a damper open due to no vaccum or corroded or foam seal needs replacing

Yes the seal has nostrils that can close and open if wanted.
Open, unplug, or unseal. Those are opposites of seal.

Calligraphy, painting, and seal carving
No, painting over mold with Kilz may temporarily cover it up, but it will not effectively seal or remove the mold. It is important to properly clean and treat the mold before painting to prevent it from coming back.
Platelets are the cell pieces that form clots and seal up cuts.
The Dodge Neons suffer from water leaks around the rear tail light areas caused by the foam seal and/or trunk seal weatherstripping leaks. Solution is to pull the light out, apply silicone seal to the foam seals and put them back on the car. The trunk seal can be done in similar fashion. This is a known issue.
I've tried that many times and never found a reasonable method.
