Hello.

First time poster.
Complete newbie to interior auto restoration.
----
1995 Saturn SC2
Project: Reattach Original Fabric Inserts and Reinstall on Door Panels

(I will be adding pictures after this initial explanation -- these will make this summary make sense.)

The WHAT:
Fabric was bonded to a stiff woven material matching the exact shape of the fabric piece. No wraparound, only to the back edges of the stiff woven material.
The stiff woven material was then attached to the door panel with adhesive from a glue gun (?)

The Questions:

ADHESIVE and APPROACH (fabric): I see many recommendations for 3M90 due to its bonding strength when applied property. Normally, that would be fine for me, except the shape and internal cutouts, plus the requirement to get the fabric precisely aligned at the edges of the woven fabric since there is no overwrap to the back, makes the placement of the fabric absurdly difficult on the first try since you don't get a second with 3M90.

• Is there a better choice for an adhesive that will allow any shifting once the fabric is applied? I'm pretty sure putting the surfaces together before both dry is a big no no. Whatever adhesive I use needs to withstand the 100+ temps in the midwest and east coast

.

PLACING THE FABRIC: Ordinarily I would think working in sections out from the center would be the best approach, but the slightest tilt there translates to a large deviation at both ends. I've considered trying to align the top edge and tack it in place, then raise the fabric back over that edge, and place from top to bottom. This should guarantee a close alignment, but I do not know if the stiff woven material will flex enough to allow folding back of the material (very thin and soft)

ADHESIVE AND APPROACH - Reattached Fabric + Woven Material to Door Panel

Planning to use an Infinity Glue stick. The factory glued only the edges all the way around plus the cutouts.

I've tried to provide enough written info to almost understand my goal and my needs.

Next come the pictures. Quite a few to show shapes, textures and size.

Sloppy alignment around through holes is necessary because fabric has been stretched longitudinally and the handle and switch will cover those misalignments

Door panel.
Note groove/channel around the fabric mounting area. This makes it a bit unforgiving if the alignment is not close to perfect although the entire fabric panel is slightly recessed into the door structure.

I'd use Weldwood contact adhesive over the 3M stuff. Not sure about 3M 90 but over 3M glues from a can I've used didn't hold up over time very well.

I know Weldwood offers it in a aerosol can but I've never used that. I buy it in gallons cans and spray it with a HF gun.

To glue the fabric to the backer, I would place it over the backer, making sure it was properly aligned. Then lift one half and spray glue on both parts. Let the glue tack up then carefully massage the fabric in place starting from the folded part to the end. Once that side is glued, repeat for the other side. Lay some craft paper or something similar between the folded pieces of fabric so you don't need to worry about over spray.

Sorry, I have no advise for adhesive to use to glue it back on the door panel.

Thank you kindly.

The 3M90 is a spray contact adhesive. like the headliner adhesive sprays, but 95% of the users do not read the instructions and try to use it as a glue. Even when misused (wonder how I know), it still held some stuff in the car for a good 3 years. Anyway.

With the Weldwood, will there be any chance at repositioning the fabric and or backer once they touch or is it one and done.
The answer will not dissuade me -- I just need to know what to expect.

Thank you also for the attachment "strategy."

I feel like cutting out 10 pieces of cardboard and 10 pieces of similar fabric and screwing those up as practice.
The only source of this fabric and backerboard is in 30 yr old non-rusted out 1st gen saturns down south and in the southwest.

Thanks again.

I'll be back to post the outcome

I have been able to reposition with the Weldwood. Don't press down on it before your sure and make the decision quickly though.

Practice pieces are always a good idea.

It looks like there are trim pieces that go in the cut out areas. If that's the case I would concentrate on making sure the edges are aligned properly.

Indeed the cutout alignment is important. However, I accidentally stretched the fabric years ago during a botched on-car repair, so in order to not have excess at one end or the other, I have to cheat and make up for the extra material there. The "flat side" looks ugly if it overhangs; the pointed side you really can't see, so it's all being shifted in that direction. the switches and handle outer trim will hide that.

The worst part of aligning this is the top and bottom edges. The fabric as attached at the factory is glued all the way onto the sloped edges of the backing board. There is no room for error. So I'll use the top edge as the primary and pray I don't start off on an angle, although that quickly becomes evident.

Why so much effort on this old Saturn?
Drove it off the lot in 95.
244K and one engine later, it's somehow not rusted out, and I thought it would be fun to take to car shows when fully restored. Already registered as an antique. NOS factory headliner in the basement, seats fine, everything works.

Would like to have an early 70s Chevelle, but not gonna happen, so...

You’ve got a small window with Weldwood—quick decisions help
If trim’s covering the cuts, prioritize precise edges

It is called OPEN time in which you can lift and reposition fabrics if you need too. I think if you are going to use an aersol can and want to be 100% sure of the strength of the bond I would consider Lepages Upholstery Contact Cement at Home Depot. It will tell you on the can how long you can mess with repositioning fabrics. Try and do it right the first time.
