70 door weatherstrip install issues

Recommended Posts

Working on this 70 convert and having issues with installing the door weatherstrip. The weatherstrip is a Carpenter product and looks nice enough. Issue is this: The weatherstrip has basically two sides that are at a 90 degree angle to each other where it contacts the door.. The problem is where it sits on the door , the door isn't a 90 degree angle..it's a much wider angle as one side 'leans back' more than the other. If you glue both sides of the weatherstrip then one side sticks and then pulls off while the other gets pressed and vise versa....had the vertical portion of the door  done and had to remove it...remove the weatherstrip adhesive and now ready to put it back on again but was wondering if in fact i should just glue one side of the angle and not the other???

Anyone run into this? Why couldn't Ford make push in pins in their weatherstrip similar to GM and no issues. lol.

Thanks...John

Can you post pictures of the areas that are giving you hard time? The aft and bottom parts of the door has 90 degree angle for weather strip, but the front part of the door is flat.

Will do...thanks.

So...the one pic shows where the weatherstrip sits..in that angled portion. The 2nd pic shows when i hold the flat side of the weatherstrip to the one side, the other side opens up. The 3rd pic shows when i hold the weatherstrip flat against the area by the lock the other side opens up. It's like the original weatherstrip might not have had a perfect 90 degree angle to the two flats that glue to the door. This is the original 70 door and clearly you can see that the angle where the weather strip goes is greater than 90 degrees..it's wider. Wondering if anyone has run into this. thanks..John

@Rcodenewf, it has been a long time since I installed a reproduction w/s (which I assume is what you are using). I looked at a few original doors I have with original w/s on them and on some one end of the w/s is little lifted, some are laying good; lifted ones did not have glue under lifted areas. If your w/s is a good quality (ie soft) then when you glue them, they should confirm. Follow the directions on the glue (ie put it on both sides, wait X minutes for it to get non-tacky etc). Last time I installed door w/s a couple years ago, I re-used the original w/s I removed without damaging it. I used the black 3M which I think holds a little better than the yellow one; do the aft side of the door first, then half of bottom, then other half, then front and glue it in sections. Before gluing, I install it with masking tape and mark the w/s and door in a few places so the ends of w/s matches to the screw holes at both ends of the w/s. Then glue section at a time, and attach per the marks I made on door and w/s. Attach one flat side of the 90 first while butting the 90 degree to the door 90 degree then press the other flat side. If you follow the directions on the glue and if your w/s is soft, glue will confirm the w/s to door. Good luck.

Another tip, wipe the gasket over with solvent, there is residue of the mold releasing agent that need to be remove to allow the glue to hold properly.

Thanks for the response aslanefe: Are you saying you glued both sides of the 90 on the vertical pieces..seems hard to do as when i tried it one side pulled away while i tried holding it to the other side of the 90?

unilec: yep.i wiped it down with acetone to remove that release agent.

John I put the glue on both sides of the "90 on w/s" and both sides of "90 on door" where the w/s will be positioned. I follow the directions on 3M "black" w/s glue and let it tack. Glue sticks very good if you follow the directions, you will leave pieces of w/s on the door when you try to remove if you misplace the w/s while installing. That glue is kind of a one shot deal, when done right almost impossible to remove the w/s without tearing pieces; that's why I mark the door, w/s etc before applying the glue. You may want to mask the area on door where w/s will be installed so while you are putting glue on door you do not get it on visible areas of the door as it is kind of a pain to remove the residue from the door.

If you can wait a day or two, I think I have a set of door w/s on my spare parts bin; I'll to post you pictures of the glue and where to apply the glue on the door and w/s etc.

Aslanfe.. yep..a few days won't hurt me to wait. Thanks

John,

Marking the door and W/S are pictures 1 and 2. Mark with reference points every 10-15 inches after you install the screws at the ends of the W/S. Also mark the door perimeter where W/S is going to be, I used red thick sharpie so it is visible for pictures (use thin sharpie for actual work). then remove the W/S screw at the front of the door.

Pictures 3 and 4; the masking tape is where you put glue on W/S and door. Dashed lines on W/S and door are 90 degree corners. With W/S screws installed at the aft end of the door, put glue 10-15 inches (between your reference lines you put on W/S and door in pictures 1 and 2).  When glue is tacked, start pressing the W/S 90 degree to door 90 degree first, then face 1 (which is the narrower side of the 2 faces), then press the face 2. Getting the 90s on W/S and door to match good is the key. Also, make sure your reference marks on W/S and door match closely while you are joining the W/S to door, if not you will end up with access or be short on W/S when you get to the other end.

I use 3M 08008 black W/S glue as in my experience it holds stronger than yellow 3M glue but it is less forgiving if you misalign and have to remove to reposition.

Don't mind the old W/S residue on the door, it was hard and going to take too much effort to clean just for pictures.

Aslanefe: Finally getting back to you. I learned a few new cuss words installing these weatherstrips..lol but I got it done.

As TexasED says the tape at increments is a very good idea. What i found out is to not to try to do too much at once.

I fastened it at both ends...marked the door and weatherstrip at roughly 1foot intervals...then starting at the rear of the door i did the vertical strip in two steps and then the segments under the door. One has to be very careful not to tug on the weatherstrip as it will certainly want to stretch and misalign your screws on the front of the door.

The lower corners were the toughest but in the end it worked out well. A few spots didn't take so i pulled the weatherstrip back, pinned it back with some good 3M body tape and then got in with some fresh glue using a soldering brush ( i bought a whole pack to do this..inexpensive) ...allowed it to cure a few minutes then pressed the weatherstrip back utilizing the tape again.

After letting it sit for that evening and overnight , i finally shut the door. I warmed the weatherstrip..especially the ends..with a heat gun and this allowed the door to lock in further on the latch. I left them there. 

Thanks for all the help guys. Hopefully i can help someone out with other issues they're having with their stang.

Best regards, John

On to next hurdle then,; yes it is tedious work to get the W/S right, have it last and not let go real soon. I usually wait for a day that I am real calm to do the door W/S, feels like it is a lot easier to put a back glass on a coupe all by myself than doing door W/S.
