Original owner had headliner replaced. I can see through the rear window a Velcro or generic hook and loop used to attach headliner to body. It does not hold.
1. What is the best hook and loop product to replace this with?
2. How many attachment points should I expect? (How much product to order)
3. Is this a DYI or better subbed out or should I go with a new headliner if I have to take the interior apart?
The edges all around are not satisfactory

 

My headliner is good but I had a bad one on a range Rover . Took it out scraped all the material and glue off it and painted it with textured stone paint..perfect ..no body ever looks up.
