Do i have to use headliner material or will it stay if i do not use that type material?
Do i have to buy material with the foamed back for the headliner. Will it stay if i do not use that type material.
If you use a heavy material such as. . . lets say, vinyl, it has a tendancy to fall after a short time because of the weight of the material. Headliner material is a very lightweight type of material and has the foam backing, which glues to anything extremely well. I would advise you, if you want the job to last for a long time, use headliner material, or something equivalent. But, you can use anything that you would like; after all it is your vehicle :~)
