I fixed my door closing issue

[1970pelle]

On my 86 c10 both door were very hard to shut with windows in the up postion.I removed both door panelsand started cleaning and lubing.What I found was my truck has been undercoated.I mean undercoated they drilled holes everywhere.They plugged the holes with the correct plugs.The vent baffles(I think thats what to call them) in the bottom of my doors were covered with undercoat and not allowing the vents to vent.So Cleaned the up .Door shut as designed.The one bummer is I found what at one time was the OEM window sticker inside the drivers door.The years had taken its toll.Looks like the clean up guys at the dealership razor bladed it off and let it drop inside the door.
