So, I am trying to figure out more on redoing my Model A's interior. I am now up to an adhesive choice. I will need to glue vinyl to panels and also glue the 4x4 vinyl headliner to the foam I already have, then the foam to the masonite liner that is already in the car. So headliner and side panels. I will not have access to a spray gun adhesive system.

At the moment, my local choices seem to be:
3M yellow super trim adhesive (spray can)
NAPA/Permatex Heavy Duty Carpet and Headline Adhesive (spray can)
Weldwood Contact Cement (brush-on)
Loctite 200 Spray Adhesive
3M Super 77
a vinyl supplier also suggested 3M 80-which I could order in aerosol cans

Advice/commentary would be appreciated. Thanks

Adhesive

Hello, I would use the 3M-90 or the 3M yellow if it comes in a spray. All the others would release in the Heat of the day, hope that helps.

First of all, there is no glue you can buy at a home improvement store that is intended for use on a car interior, so stop looking at Home Depot.

This is an upholstery project that requires high heat resistance, and holding power. The best way to do that is to use bulk (in containers of a gallon or more) HHR (high heat resistant) spray grade (shoots out of a spray gun, not an aerosol) top and trim contact adhesive. My favorite is DAP Weldwood top and trim adhesive. There are other companies that make good adhesives, like 3-M, but the DAP is way less expensive. You will only find this in upholstery supply companies. Here is one place that has it on line: http://www.yourautotrim.com/noname37.html There is no aerosol on the market that will compete with a contact adhesive of this kind. One other caution: 3-M 77 does not work at all, period, it is terrible stuff. 3-M 08090 super trim adhesive in an aerosol is very good, but still not as good as spray grade stuff, and is also very expensive.

Look at this Wiki article, it will tell you everything you need to know: http://www.crankshaftcoalition.com/wiki/Contact_adhesive The solvent for this stuff is mineral spirits, or Xylol. Xylol is more powerful than mineral spirits, but it's also at least twice as expensive.

Thanks. I don't have a Home depot near me-I looked at NAPA and a couple of other parts stores.
The DAP Weldwood HHR Contact Cement you cited says that it may damage some vinyls, so how would I tell if my vinyl and this adhesive are compatible-before I invest in the glue and a spray gun system?

 

[DanTwoLakes]

I can't imagine any vinyl that would be damaged by it. I have used it for years and never had any problems. I think DAP is just covering their own *****.

I agree with Dan for using that glue it is cost effective, I have upholstered many aircraft interiors and certified and inspected them, and not allowed to use that glue because it is corrosive to aluminun. My favorite and expensive contact adhesive is 3M 1357, and FAA approved, great glue because i hate waiting for glue to setup, better have it right the first time. The worlds best glue.

I have to say..DAP Weldwood top and trim adhesive is the best out there..:thumbup:

 

[jsm1847]

I'm going to third the Dap Weldwood...
A few years ago, when starting the business, I was doing headliners, reglues, & mainly repairs. I used two or 3 different 3m products and they would fall off. I used the weldwood once, stuck like none other. It's cheap too...

3M spray adhesive is great for headliners and vinyl . It is fast tacking and you should have a helper to hold up the material asyou spray in one squarefoot sections. a small soft paint roller will help keep out air bubbles. I have 35 yrs as an autobody tech,

Thanks for your input. I especially like the idea of applying adhesive as I go-I was trying to figure out how to spray the entire line, then fit it into the car without getting adhesive everywhere and still get the liner positioned correctly the first time.

wish i had read this before i did my project i agree with the comment that NO rattle can will hold up in the heat. i learn by trial by fire

You don't have to spray it, you can also brush it on.

Are you referring to the DAP Weldwood you recommended here? Do you know anyplace I could buy I quart? I probably would not use/waste 75% of a gallon doing one small Model A coupe interior. Thanks for your help.

 

[DanTwoLakes]

Yes, DAP Weldwood Top and Trim adhesive. I would find an upholstery shop nearby and ask to buy a quart. I buy mine in 5 gallon buckets.

I inquired of DAP last week on the Top & Trim Adhesive for use on Sintra board (PVC Sheets) which I am using for all of my interior panels. Jessie, one of their Product Specialists responded with: Unfortunately, we do not recommend the DAP Landau Top & Trim for applications involving PVC or plastics and it may damage some of these surfaces. Testing is recommended before using in a large scale application. Dan, I just read in this post and in a previous thread that you use this on PVC to foam, fabric, vinyl, and/or leather without an issue. Based on DAP's response, I was about to go out and buy traditional backer board and redo my panels... please tell me I don't have to do this!

 

[beachbum jim]

you dont have to worry about it. I have been using DAP HHR for many years with many different materials PVC included with no problems. Im sure Dan will agree. Regular backer board, even the so called waterproof will warp. I ordered some for a non automotive project and it was delivered warped.

 

[DanTwoLakes]

You don't have to do that. It does not damage PVC foamboard.

 

[udtoy]

Thanks guys. I can always count on getting the real scoop from this forum!

Ok so assuming I can find an auto upholstery shop who will sell me the DAP adhesive, how much do I need? Counting headliner glued to foam and foam glued to board, doors, kickpanels and the sides and rear of the cab I have about 25 square feet. If I use it as a brush/roller on, will a quart be sufficient?

I fi am "gluing" the vinyl to ABS/PVC for the sides and back, is it glued only where it's folded over the back, or am I gluing the entire surface of the backing before applying the vinyl? Thanks

 

[DanTwoLakes]

O.K., I am at a loss to understand why any of you can't spend $30.00 to buy a gallon of the best glue on the planet. If you use half of it, all of it, or none of it and throw the rest away are you still not in the same place financially? If you can find an upholstery shop that will sell you less than a gallon for $30, and you need more to complete your project, where are you at? If this was a question of spending $5 more to make your paint job, transmission, engine, or whatever there is to spend on your project of a lifetime, would you spend the $5.00 or not? This, my friends, is the definition of a no brainer.


Why is the interior of your car, where you will spend 100% of your time when the car is finished, the least important thing you spend your money on?

If I had a nickle for every $10,000 paint job on a car with a $500 interior that I have seen, I would be one rich sum*****.
