Teardrops n Tiny Travel Trailers

Has anyone tried to use automotive spray on trim adhesive. Like 3M 8090 headliner adhesive. To get the canvas to stick to the interior ceiling panel. That stuff gets real tacky (holds car headliners). Then once the ceiling canvas is staying up, proceed to paint on the TB2. Just a thought/ just asking ?
This is just a thought for when I get to the point of needing to attach my canvas to my interior ceiling. The 3M could hold up the canvas (very tacky)... until you get the TB2 applied. Or maybe just a dumb idea. Would not be my first

No idea is dumb , but just needs to be tested ...

The spray adhesive would seal the wood when dry. I don't think the TB would penetrate the wood.

Time for testing like GPW said.

Gosh guys , for my money , I was trying to get away from those smelly spray adhesives... First , they're a bit pricy , and from experiences years ago , in exposure to heat ( sun ) the adhesive outgasses and actually melts the foam a bit ... ( 3M77 tested on Balsa covered foam wings ) ...
PLUS , it’s just not that difficult to lay a piece of material on the ceiling with TB2 ... ( If I can do it , anybody can do it !!! ) .. Extra pair of hands helps ... The trick is to cut your fabric to size , leaving just a couple inches on each side ... then roll up the fabric into a roll ... Then you can start at one end , generously apply straight T2 to the ceiling (foam) , and start to stick one end of the roll down at your starting point ... Your helper can hold the roll while you press the fabric into place with a small squeegee ...and hold and unroll as you go ( easy work for the helper ) ... Without a helper , you need to make a T stick out of scraps , something the right length to hold up the roll while you glue ... ( more diffcult)

One point ... ( here it comes ) if you use something to stick the fabric to the foam at the starting point , it won’t try to detach ... I used Blow gun darts as they were Big , easy to work with, and had orange tips I could see...

Ps. if the fabric wasn’t pre shrunk , you might want to leave extra fabric all around to trim ... and be prepared to go back and squeege ( press down) the edges again ... and again ...

I tried several spray adhesives and they all melted the foam to about half its thickness.
For use on plywood sure, but i dont see spray adhesive as something permanent. They seem to loosen with heat and flexing.
