I am not sure why the web site is still available, however, if you page through ford trucks on the website, 1948-55 you can find the picture of one of the headliners (not lined-black ABS) in a 48-50 truck and you can see the corner that I am referring to. I did buy a siphon feed glue gun and have a quantity of the Weldwood (Dap) landau top and trim contact cement. I have test sprayed with the gun and it does not seem to be adjustable to get a nice even spray pattern. It seems to "spit" a bit rather than getting a nice even spray pattern like paint sprays. Am I expecting too much?
After looking at the photo on the website do you still think that I can be successful getting the headlining material to form to that corner?
