Review on Pre Caulking Filler Backer Length Width by Don Leblanc

I inserted this 3/8" tube into all 5 of my door seals (first remove the seals and stretch out on the floor and then used to insert the coax cable, then tape the foam to it, then thread the foam tube through the small holes that each door seal has) Just don't do more than half of the seal at a time or the foam will tear. I have used lotion to lubricate the cables and foam to reduce friction in the seals. My doors now close nice and tight whereas previously I could dent my doors after closing and they could be pressed harder against my car , and before that I had a bit of wind noise in the driver's door And the main purpose of these tight seals was to improve the sound pressure readings in my car! =)
