Coupe interior roof options

[Cincy123]

I’m curious as to what DIY products folks are using to cover the interior aspect of the Coupe body rather than installing the provided headliner fabric material. I was thinking of some type of bedliner product (herculiner or similar) and would like to hear what recommendations people have for this area.
Thanks

Sprayed UPOL Raptor as the headliner in my Coupe. I didn't want to mess with the provided headliner fabric either. It basically disappears above the roll cage. Extremely pleased with how it turned out. Same material, BTW, used for the entire underside of the body, wheel wells, splash guards, hood, etc. Highly recommended. Superior IMO to the traditional air dry products, e.g. Herculiner, etc., because it's a 2-part catalyzed product and is really tough. Available in other colors besides black too.

Raptor X 2. As Paul said it’s available in colors but it can also be painted do can match the exterior if that’s your preference.

Wow, I used that stuff on my MK-4; however, I didn't realize it was paintable.

Does the raptor have a hard feel? Or is it still rubber/flexible when dry?

Definitely on the hard side. You can't really push your nails into it, for example. But flexible enough that it's not brittle. Sold as a truck bedliner, among other things, so needs to be hard but slightly flexible so it doesn't chip. Exact feel as Line-X, if you're familiar with that.

Thanks Paul. Looks like Amazon sells it with a gun as well in 4 liter kits. How much product did you use to do all the areas you described? Did you apply more than one coat? Did you apply a primer first?

I initially purchased the 4 liter liter kit with the "free" spray gun. Being careful, that was enough to put 2 coats on the underside of the body and hood including the interior roof. I would consider two coats to be the minimum for decent coverage. I later had to purchase another single quart kit for the splash guards and some touch-up. My recommendation would probably be 6 liters and a coat or two more in the wheel wells than I was able to do with the amount I purchased. But having said that, hasn't been a problem.

Now about that "free" gun. It's an undercoat aka Schutz gun. It kind of flings the material out with minimal atomization. I played around adding just a bit of reducer and was able to get it to spray reasonably OK by playing with the air pressure. U-POL also sells a higher end adjustable gun, their part number UPL-UP4880. I purchased one of those and used it to spray the same material for my truck build. It's a significant improvement and allows you to adjust the spray for a smoother texture. Either way, I'd recommend staying with one of their guns. They have the proper cap and tube length to go directly onto the liter bottles of material after you add the catalyst. It's a nice system that works well and reduces the amount of clean-up when you're done.

Looks like they also sell a primer, is that necessary for this application?

No primer any time I've used it on fiberglass and adhesion is no issue. Just roughed up with 100 grit or so and cleaned up. Per U-POL's instructions, it appears the primer is mainly for bare metal.

I used a 1/2" thick layer of foam against the actual inside of the roof and then glued on the FFR supplied foam backed black cloth headliner.

I wanted some level of insulation from the heat of the very likely hot roof from the Arizona sun and then the typical car headliner but in black to have the roll cage blend in somewhat.
Additionally, I wanted some level of sound absorption from both outside sound of the rushing air and interior sound of the sidepipes, etc. that would otherwise reflect off a solid hard roof ceiling.

Specifically, I used from Second Skin Audio, MegaZorbe Hydrophobic Melamine Foam, 1/2 inch thick with adhesive pre-coated on one of the surfaces + peel off paper. Four 24"x24" pieces were bought.
The adhesive used was incredibly sticky. I conducted a stick test of a 1/2"x1/2" piece and could not remove it without complete destruction of the foam and adhesive. Even solvents and a razor blade were needed for removal of the test-piece and it was still difficult. It's absolutely necessary to have your cut pieces for placement on the inner roof pre-made with patterns and quite precise. then carefully laid down. There is really no repositioning at all. Edges can be trimmed with some effort.

I glued on the FFR supplied black fabric with thin foam backing headliner with Sprayed on 3M #90 High Strength Spray Adhesive. It had a higher temperature rating than other similar 3M spray on adhesives.

I placed these on the full rectangular section of the roof above the drive/passenger area plus up the A-Pillars.

All of this was accomplished with the cabin body off the chassis, upside down on padding on the floor plus some extra padding underneath to stabilize. The inner cabin roof fiberglass was hand sanded with 60 - 100 grit and cleaned with thinner.

When everything was glued on and a day had passed it all seemed totally secure. Time will tell though.

Just throwing an idea out there. The Raptor looks like a really tough product and leaves a nice texture. I wonder how flocking on top of it would turn out? I flocked the inside of my glove box (details here (https://thefactoryfiveforum.com/showthread.php?31167-Greek-Guys-Garage-Roadster-Build-9509-(Picking-up-the-chassis)&p=473648&viewfull=1#post473648)) and am very happy with the result. it's a nice velvety finish, like the inside of a jewelry box. As a headliner finish over the Raptor I think it would have an alcantara-like look.

Here's how Flock It recommends finishing large parts like dashboards and headliners: https://www.flockit.com/images/what-is-flocking/How-To-Flock-A-Dashboard.pdf

^JohnK, I had my dash done in a textured black powdercoat. It looks beautiful and is similar to the texture of that flocked image, but... I assume, more durable and easier to clean since it's powder.


For positioning the high-stick SecondSkin insulation, I wonder if spraying windex on the surface first would help give a few seconds of positioning before the glue adheres. We used to use windex on the vinyl labels for medical devices at my old job. They'd spray the plastic device case, place the label and slide it around until it was centered, then the windex would evaporate and the glue would permanently bond it to the plastic case.

I have used flock on a 35 roof and 818C roof with, IMO great results.

Do you remember how much flocking was required for the 818? I am interested in this for my coupe.

[I] bought a 1lb bag of black suede-tex flock and 16oz can of black adhesive.

Hello,
I decided to not use the FFR supplied Headliner Material. I wanted what I thought was a better way to absorb interior sound and block heat coming from the roof.

The products I used were:

1. Noico Green 170 mil 18 sqft Car Waterproof Sound Insulation (purchased through Amazon)
Amazon.com: Noico Green 170 mil 18 sqft Car Waterproof Sound Insulation, Heat and Cool Liner, Self-Adhesive Closed Cell PE Foam Deadening Material (1/6'' Thick Sound Deadener) (https://www.amazon.com/gp/product/B07CZ2DHV3/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)

2. Permatex 27828 Spray Adhesive.
Amazon.com: Permatex 27828 Body Shop Heavy Duty Headliner Adhesive Aerosol Can, 16.75 oz : Automotive (https://www.amazon.com/Permatex-27828-Headliner-Adhesive-Aerosol/dp/B000HBNU9K/ref=sr_1_1_mod_primary_new?crid=XGSTA0EZSLQA&keywords=Permatex+27828+Body+Shop+Heavy+Duty+Headl iner+and+Carpet+Adhesive+Aerosol+Can&qid=1666740985&s=automotive&sbo=RZvfv%2F%2FHxDF%2BO5021pAnSA%3D%3D&sprefix=permatex+27828+body+shop+heavy+duty+headli ner+and+carpet+adhesive+aerosol+can%2Cautomotive%2 C175&sr=1-1)

3. Bay AC301-5 Auto Carpet- Black (purchased from Amazon). This carpet does not have a backing and is flexible enough to conform to corners and compound bends.
Amazon.com: Install Bay AC301-5 Auto Carpet- Black -5-Yards : Automotive (https://www.amazon.com/Install-Bay-AC301-5-Carpet-5-Yards/dp/B001JSY7BU/ref=sr_1_3?crid=1RQLO4RS5ZMV&keywords=Bay+AC301-5+Auto+Carpet-+Black&qid=1666740778&s=automotive&sprefix=bay+ac301-5+auto+carpet-+black%2Cautomotive%2C155&sr=1-3)

My steps were:
1. Apply the Noico panels to the cabin side of the roof.

2. Spray Permatex 27828 Body Shop Heavy Duty Headliner and Carpet Adhesive onto the carpet. Spraying the adhesive onto one surface allows working time.

3. Apply carpet, using a laminate roller to firmly press the carpet.

4. Additionally, I fabricated an overhead storage tray from 3/16" ABS that I heat formed to shape over a wood buck I fabricated. I then covered all surfaces with the same carpeting material.

I used the FFR stuff and 3M adhesive. I blended all of the edges to a round shape using foam thus making for a cleaner installation. This was after the heat insulating pad that was self adhesive.
