Would plastidip work as a sound absorber?
If I remove my door panels, cover the lock and window mechanisms, and sprayed the inside with plastidip, would it work as a sound absorber or would I be better off getting actual sound stuff or dynamat? Its rubber coating, so I would think it would be ok and do well but wanted to ask first before I try it

Thumbs up for the idea 
. Something worth thinking about.
If it is for your actual metal part of the door ie vibration not rattling:
It depends on the specific weight(ie the weight per unit volume - heavier is better) and how that stuff holds up to the changing temperatures and moisture. If it runs down the inside of the door it might clog the drain of the door.
You could just spray it on something and put it in the oven at 80°C to see if it runs (keep the surface vertical). Put it in the fridge or freezer (depending on the minimum temperature your car will see) to see if it cracks. Repeat with added moisture (spray on for even distribution and keep wet). Check how the material is faring when drying up and dried up.
I think the inside of the door is coated already against corrosion, which might interfere with the plastidip coating. There are plastidip products specifically made for metal.
If it is for your door panel ie rattling not vibration: I think plastidip would be too thin and if thick enough not mold around the uneven surfaces well. Use a sheet of SOFT foam (again suitable for environmental conditions - should not get moldy) and attach it to the back of the panel (double sided tape). An example is the foam used for sound deadening floors (click parquet) with floor heating. That is dirt cheap and works fine. It should not be flammable.
Usually all stuff you use in cars has to comply with specific standards. Once you know that standard (eg DIN) you know what to look for.
Keep me posted on what you did. Good Luck!
