Annoying headliner.

I don't own a Honda, but the question would pretty much apply to any car. So, here it is: My headliner in my car is starting droop in spots. They aren't big spots but they are noticable and it bugs the crap out of me. Does anyone know what I can do to remedy this, short of replacing the headliner?

They make some thumb-tack kind of things that are colored to help match the headliner. I think they are available at most auto stores, but i'm not sure how well they work.

i've seen kits that have a hypodermic needle type injector thing and adhesive. just fill it up and stick it through the headliner and squeeze a little bit in different spots onto the roof. then just stick the headliner back up onto the roof. Once it dries its as good as new. and no holes cuz the injector is pretty fine. Anyway like I said I have seen these and I know they work I just can't remember where try your local auto store or something. maybe ask and they will know what i'm talking about.

Thanks guys:bigthumb:
