So I have finally gotten off my lazy butt and gotten the remaining nasty Cessna glue removed and the interior primed (pictures to come later on sometime, it was too dark to get good pictures by the time i finished last night). I have been searching around a bit to try and find a source for the 1/4" Selkirk foam to finish off the interior, but I can't seem to find it anywhere. Anybody know who currently sells it and where to buy it? Thanks!

I used this stuff. I used some without the adhesive back and some with it. Sprayed contact cement on the airframe before putting the adhesive backed on just to ensure good adhesion. I used 3/8".

Just call Selkirk and order some direct. They cut it from a roll thats about 54 inches wide, and you tell them how many linear feet you need. 1/4" or 1/2" thickness.

Perfect, thanks! Didnt see it on their website, but that makes sense.

Definitely just call and order from Selkirk. Also, I’ve heard from another BCP member that ordered 1/4” foam from aircraft spruce and he said it wasn’t as good of quality.

Sounds like you got your answer so hopefully you don't mind if I derail this a bit..

In response to people using adhesive to stick the foam on, or contact cement, has anyone had to go through removing the stuff? Does it tear up the paint that you all worked so hard on or is the adhesive the weak link, or does the foam just turn to shreds? Has anyone done other methods of attaching it that are more removable?

Thanks

I love Selkirk foam but did have a little struggle keeping it attached. I originally used the recommended 3M spray adhesive but when July hit I ended up with a bunch of sagging, to the point that I tore everything off. My next round was with Super Seam Seal Ceconite fabric glue and I haven't had any problems with sagging since. The only caveat is, if you haven't worked with fabric glue before, it's very unforgiving and dries extremely fast and takes a little technique to apply evenly, I used a small roller and applied the glue to the foam. It's also easy to get glue all over. A ton of masking on everything worked well for me. I also used Airtex headliner material over my foam just to give it a more finished look. That worked well but was difficult to roll under on the edges and I'm still not totally happy with it. There may be a round three in my future.

Derail away! I guess now that I know where to get the foam, I'll need to know how to attach it or remove it as needed...

Super77 3M spray is ok, but it doest really do that well as you point out. The best way to install the foam is with 3M 1300L. Most of the issues I see is with prep and application. first, make damn sure you have a good prime underneath. DON'T put adhesive to the bare alum. I would also recommend you used a good catalyzed epoxy primer and NOT rattle can, especially zinc chromate. Make sure it is not a porous primer and can stand alone as a topcoat. Boeing BMS-10 is a fantastic primer.

Next, brush on the 1300L onto the back of the foam and let it pretty much dry. While its drying, paint the panel you are working on, making sure you let it tack up good... you get one shot at putting it on, so make sure its lined up perfect, then press it on. If you do this, the stuff will pretty much NEVER come off... and the next guy will curse you. LOL

I bought mine from 'Spruce as others have mentioned. It's a lesser grade material but I laminated mine with a layer of felt.
To attach, I used sailmaker's basting tape around the perimeter and a few lines in the middle. More or less 2" spacing. On a painted surface, it will stick forever but is still considered removable. Pulling the foam down will tear off the surface of the foam but you can re-apply the bastig tape to stick it back up.

The felt added a bit of rigidity to the panels that helps to keep them in place on their own.

Here is an interesting site with a lot of information about sound foams and aircraft and other things.

As pilots I know we read and follow the instructions on stuff to the letter. As mentioned above, make sure your adhesive is in the proper stated, let it dry as need be then put it up, to wet, na, wont work.

I have used barge contact cement with great success, however, not on aircraft, just boats, rafts, trailers, other stuff.

I can’t understand why everyone is so set on using uber adhesives to attach foam. I have the self adhesive foam from spruce and it stuck just fine. I wiped everything down with denatured alcohol before attaching. Nothing moves. I didn’t strip any of old adhesive. Why take it off if it’s just getting covered with the foam. Seems like wasted time. I covered the foam with fabric using 3M 77 Spray Adhesive. Worked great.

There was some corrosion under the adhesive that I stripped off on my 206. It was nice to be able to clean it off and stop it from continuing. I would have never seen it if it weren't for removing the black adhesive.

Well, I guess everyone should start tearing out their interiors so they can remove all the adhesive and look for corrosion.

A past owner sprayed adhesive onto the bare aluminum and it attacked it pretty badly.
I was replacing the skin for hail damage anyway but it was impressive to see. The skin was bright and clean everywhere else and heavily pitted where the glue was.

I never said that. But since I was so close anyway it was worth it for me. Would the skin have lasted another 40 years? Probably. Do I feel better that I took care of it in the plane that I am hauling my friends and family in? Yup.
My plane, my choice. It really wasn't that hard to remove. I wont bash others for doing it or not doing it. It's their choice.
Have you ever sprayed your wings and tail with corrosion treatment? That's a pretty common thing, and why would the fuselage be any different then the wings and tail?
