I have just finished installing weatherstripping in a '58 f100 and would like to share some thoughts with others who may want to or have done the same.
The weatherstripping was purchased from LMC. I don't know who actually made it. The adhesive I used was 3M 8008 contact type cement.
I had two major problems.
(1) the adhesive would not initially bond to the molded "style" portion of the strip,and
(2) the molded portions would not match up lengthwise to both fit as you install the weatherstrip over the top of the door. the result is one or both of the style areas were dislodged from their proper location.
My opinion is that in the process of creating the weatherstrip, the straight "normal" portion is attached to the "style" portion by molding. In that process it is common to use a mold release material, often silicon, and that I believe is the root of the adhesion problem.
I was finally able to overcome this by abrading the surfface with 80 grit cloth and wiping it down with acetone . Alcohol did not work.
The problem with the fit I ended up cutting the link between the two style sections , glueing them first then trimming the section of normal material to fit. I also learned to be very patient and let everything set clamped as necessary for a couple days before reattaching the door.
Hopefully this helps someone else so they don't have to learn the hard way. My first door I did four times before getting it right. the second door I did once.

 

Roger, welcome to FTE. Thanks for your insights.

Most people sooner or later realize that if you want to find replacement rubber parts that have any chance at all of fitting correctly, the best bet is to purchase Dennis Carpenter stuff. It is frequently sold by the other mass vendors, but my experience has been hit or miss on stuff from LMC, so I just go straight to the source to be sure. Much of DC's stuff is made from Ford molds and tooling.Steve.

 

Great tips both or you guys. I plan on doing mine when my T5 swap is complete. Thanks.

 

I used the Carpenter stuff, it worked great. Installed in one piece no trouble.

LMC has some opportunity for improvement!

 

Now, if I could just get these Depends to fit right.......

 

Do they have the elastic around the leg? They always seem to pull down on me!

 

Shoulda bought the Carpenter stuff. And I'm still peeling that glue out of my creases.....

 

I heard Carpenters nail theirs up!

 

I agree with Steve!
