Sorry, ^headliner^=dashboard

I know what kind of Russian glue you're talking about, I used it to work with the headliner. I think that's close to what J[b]ens Jesberg[/b] said. I put glue on the leather and on the plastic, then I let it dry completely. Then I put the leather on plastic and warm the leather from the top with a hot air gun to a temperature of 750 Fahrenheit. I can not activate the glue other way. The glue is activated only after the hot air gun. Sun can not make this glue soft again. I like the glue a lot for headliner. I hope, it help understand about this kind of glue. I will try sabaspray, thank you Jens Jesberg. Im sorry about my english(((
