Reinstalling cloth headliner

I used contact cement to hold the middle , front and back , then worked outwards from those points.. There is a good article by Ron Fryer, http://www.upholster.com/auto/headliners-installation.html

I brushed the contact cement onto both surfaces, let it set for about 20 minutes, then carefully put it into place.. I did not use any cement on the sides, just the points from the teeth and the inside molding hold it in place on the sides.
A hair dryer to warm up the vinyl works well when streching.

Hope that helps!
