I just bought a pair of door opening weatherstrips for my car. My question is, is a weatherstriping sealer/silicone something that definetly has to be used or will they seal fine without it?

 

There is a weatherstrip adhesive made by 3M. I have looked at the weatherstrip on mine trying to determine if it will be destryoed during removal for painting but can not tell if all of it is free of adhesive or not. Along the door edge I do not think it is glued but up near the top where the material is larger and thicker I am not sure.

The doors seal well and no wind noise.

 

any updates?

 

I ended up using a weather striping sealant and it worked fine for me.

 

Do you have any pictures or links of the weatherstripping sealant that you used?

 

I don't have any pictures of the stuff I used. It was just a weather stripping sealant that I found at advance auto parts.

 

do you know what is was called?

 

it is not necessary to use any adhesive or sealant - you can if you want to, but not necessary

 

X2...Just Glue them in where recommended and your good to go.

 

Permatex Black Rubber Sealant

 

I just installed mine about a week ago and I only used adhesive on the ends at the tops of the doors. I used the 3M weatherstrip adhesive. It's yellow but it comes in a black tube.

 

do you guys have any leaks?

 

Nope, none that I know of. I drove the car about 100 miles today. It's the first time it's left the driveway since May and I just replaced ALL of the weatherstripping on the car. It's 1000 times tighter than it was before. The doors shut solid with no more rattling.
